Hello lovett1701 .
There is an easy way to check. Please enable Core and this mod in the Mod list to see if the same problem occurs. If the same phenomenon occurs, this mod is the cause. If it doesn't happen, it's likely that it's caused by other mods.

I don't know your mod list, so I can only give you advice. Please forgive me.

I don't know why, but it's no longer letting me do a zone since the update, instead, its forcing me to do cell by cell

@ark
Thanks for the detailed report.
I see. I wasn't aware of the summoning process. It might need to be careful.

It's the spell that summons minions and one I couldn't identify from the medic/healer class (not the priest)

It only broke a single mountain roof tile above the caster's head and nothing else. As far as I could tell it only did it under mountain roofs and not the regular constructed ones. Really weird interaction

Hello ark.
In the original RoM without this patch, Meteor spells and other like spell can penetrate ceilings, so this is likely a normal feature.

Don't use this with Rimworld of Magic or any of the addons for RoM. Certain spells from both mods cause roofs to collapse on top of colonists for some reason.

Hello Djmowchicken.
Switch the ceiling layer on the bottom right of the screen to visible and check that there are different shades of color on the ceiling. After that, by specifying the area where you want to remove the ceiling, the colonists should be able to remove the ceiling.

I didn't select zone with violence. Will it still work?

Update : 12 Jun, 2024
v1.6.1
- Update compatible with the unstable version of RimWorld 1.6.4488 rev717.
- Fixed patch for 1.6.
- There is no sound for removing the ceiling temporarily. Overhead mountain does not accept soundPunchThrough.

Update : 10 Jun, 2025
v1.6.0
- Added 1.6 tag preliminarily for new DLC.

TYSM! That response time is crazy, me and gf are grateful, thank you!

Update : 14 Dec, 2024
v1.5.1
- OwO³ reported an issue where fungal gravel from the Ideology DLC could only be placed under the mountain rock roof, so added a patch for the Ideology DLC to address this issue, which lifted the restriction and allows fungal gravel to be placed anywhere.

Note :
This update may ruin the atmosphere of underground life, but if you value the atmosphere, please play by growing mushrooms only in caves.

Thanks to OwO³ for reporting this issue.

P.S.:
I'll try to create a terrain patch for the ideology DLC.

Hello OwO³.
Yes. It can only be placed underneath overhead mountain. This means that if you use this mod that removes the rock roof of the mountain, as you are having trouble with, you will not be able to use it.

You can enable or disable this mod in the mod list as needed. Changing it mid-game will not affect your save data. After removing the unnecessary roofing, disabling this mod is the quickest solution. Please try it. Thank you.

Using this is preventing me from using fungal gravel :(

Hello Chromium.
Thank you for your comment. This mod focuses on making the game faster and light file size.

Infestations are part of the game challenge so I will not use this mod, but well done, nice job still.

que será, será

Ha ha, I have no idea what was just said.

what a nice guy !

Hola pichulaRICA . Sólo voy a tomar sus sentimientos. Disfruten del juego.

HOLA ESTOY MUY AGRADECIDO DEJAME ENVIARTE FOTOS DESNUDAS DE MI NOVIA

@VoidEngineer.
I'm glad the cause was found. Thank you for your hard work in checking.

It's probably a type of mod "Geological Landforms" that overwrites existing Core terrain data when generating a map. If rewrite the map, that's the correct way to eliminate the problem.

Dll is constantly overwriting the terrain content, so it may be difficult to maintain compatibility...

If the error is only logged and it is possible to remove the roof by selecting the pawn directly and then selecting a command with the mouse, there is also a way to remove this mod from the mod list after removing it.

Thanks, Proxyer. I appreciate you for making this mod. I dug around and finally figured out that it was indeed a conflict like you suggested. Apparently it doesn't like something about this guy: https://steamcommunity.com/sharedfiles/filedetails/?id=2773943594
I'll decide what I want to do about it on my side. I don't expect you to patch your stuff unless you're just interested in doing so. I appreciate you pointing me in the right direction to resolve this.

Hello VoidEngineer.
The only patch I created is to change the remove sound and removing the roof and collapsed rocks. The part related to Job has not been changed at all.

Sorry to trouble you, but save the current MOD list and try to see if the same error will occur, with only Core, 4 DLCs and this MOD.
If there is no error, it seems that one of the mods you are using interferes.

In particular, mods that change the ceiling in the same way (for example, Raise The Roof or RoofBomb etc) are incompatible with this mod. Rewrite the attributes changed by the patch during the game. Thank you.

Getting a red error at start up and was wondering if anyone could provide some insight: "Could not load reference to Verse.JobDef named RemoveThickRoof"

Update : 14 Mar, 2024
v1.5.0
- Update tags for Rimworld 1.5.x.

Arigato El Birri - san
De nada!
Este mod consiste sólo en archivos de parche y es el arreglo más ligero. Esto de ninguna manera afecta el rendimiento del juego. Espero que este mod ayude a tu juego.

este mod si es un verdadero QoL he de decir lo siguiente: arigato proxyer-san

@Ozzy
Haha. That is correct. Although removing the mountain rock roof is manual.

To clarify, installing this mod removes mountain infestations right? because if it does thats two birds one stone lol

Hola Chifle_593.
De nada! Me encantaría poder ayudarte con tu juego.

EXTREAMADAMENTE UTIL PARA QUITAR ESOS TECHOS DE MONTAÑAS Y LIMPIAR UN POCO EL MAPA SIN EL RIESGO QUE SE PASE DERRUMBANDO EN CADA MOMENTO , MUCHAS GRACIAS :3

Updated workshop description:
Fixed download link for non-Steam version 1.4 zip.
I thank KaiserLeo for reporting this.

What!? I will check soon!

1.4 is Small Shelf?

Hello [x] ALRA.
Yes. I understand that such problems occur due to the thickness of the ceiling.

The easiest solution is to remove this mod from your mod list once you've removed the ceiling you want to remove. And add it to the list when you need it again.

It's above Rocketman and Performance Optimizer in the mod list, but it's fine to put it at the bottom of the list. Please try this. Thank you.

The mod is breaking vanilla fungal farming. Not a big problem, because you can remove the thick roof and disable the mod, but still.

@Black Fox
God is watching and he knows.

God bless you

Update : 6 Oct, 2022
v1.4.0
- Update RimWorld 1.4.3507 (unstable).

Hello Heartless #SaveTF2. I'm glad you like it!

A perfect addition to make a gauranlen tree cave.

@ichfickdich
I'll be careful.

reading this has been wild

@Zairya
Hi Zairya. Sure!
If the talent added in Ideology has an indoor desire, it should be a Mt.rock roofing. This mod will make the ceiling normal, so recommend disabling it if you don't need to remove the ceiling.

There's a problem with the mod:
While it's active, the "Indoor" need will not go over 50% and "fungal gravel" cannot be built. I don't think it's something you can fix, so better only enable the mod when one needs to remove a piece of mountain roof...

@I r b i s
That's right. From the pirates and the mechanoid factions, all the ceilings are visible with the ordinary roof. Therefore, enable Mod only when necessary.
You can remove it from the saved data in the middle or add it later.

So, the reason why drop pods destroy my mountain base ceiling is because of this mod?
