What is the correct way to revert to an older version? I need to roll back to 2.2.1 to finish a game, and I tried unsubscribing from the mod in Steam Workshop, then downloading 2.2.1 from NexusMods, then copying its contents to the Master of Orion\Modding folder but I am unable to load my games, they don't even show up in the list of saved games when I go to Single Player->Load Game.

Any thoughts?

You need to copy its contents to Documents\Master of Orion\Mods. It should show up in the mods menu in game as a "local" mod.

Doing that got the game to load, which is good. However, clicking next turn causes the game to never resolve the turn, it just keeps spinning on the first alien race's turn. All actions in diplomacy with another race cause the other race to never respond to my request, be it for technology, offering money, etc.

I tried verifying steam files for the game and some couldn't be validated and we re-downloaded, but it doesn't seem to have fixed the problem. I guess that's another save game that has bit the dust.

Edit: I found this stacktrace in the output_log folder:

It looks like it can't find a particular file, given the "filename unknown" repeated over and over again.

Stargate problem

I picked up "Stargate" as a starting perk. Works well; I could build them and the fleets used them.

As the game continues, there was a point where I couldn't build these stargates on new planets; the symbol over the planet appears soon after the colonisation, and the option to build a stargate was gone. At the beginning, I got the symbol only when the stargate was finished.

I am not very sure but I think this "turning point" came up after researching the technode, where you get the stargates normally.

I'm not sure what file it's looking for. Could you try loading it with the previous version, then using the timeline to rewind a few turns before hitting "next turn?"

I included them on the Advanced Colony Ship blueprint. Apparently star gates placed by advanced colony ship don't generate a jump connection properly. I'll have to remove that. You should look for the star gate as a built structure on those planets, scrap it, and built it again.

Ok thanks; it was really a very good idea...

Edit:
I found this in "ShipHullTypes.yaml"

colonizationStructures:
- structure_colony_base
- structure_automated_factory
- structure_hydroponic_farm
- structure_research_laboratory
- structure_jump_gate

If I delete the last line ( structure_jump_gate ), is that ok? Or do I have to delete any other lines too?

Economic Victory doesn't work with this mod (for me).

I just finished a 1v1 game vs the computer (no other mods loaded) and the very last turn before victory will never finish. I let it run for an hour, tried saving and reloading, nothing fixed it. Everything else seemed to work fine for me.

I tried, and unfortunately it didn't work. I'm just going to download the latest version off Nexusmods and not use Steam Workshop since it pushes updates without notifying you. Unfortunate, since it's so convenient, but it really should have an auto-update option that you can disable for subscriptions.

My mod doesn't change any settings related to economic victory. What was your GGP and stock market share, and how many opponents were you against?

Okay, sorry I messed up your save. I wish it didn't auto update, but there's nothing I can do but try to notify people of major updates in advance. You won't run into this problem with Nexus mods for sure at least.

My GGP and stock market share were both around 90%. I was playing 1v1 vs the computer so only one other computer. I got the notification each turn saying that I was 5,4,3,2,1, etc turns away from winning via economic victory. It was just when I got to the turn when it said I was 1 turn away from victory that it messed up. I didn't get any error message, that final turn just would never complete after I clicked the end turn button.

Edit: I want to clarify that I really like and enjoy this mod. Thank you for all your hard work on this.

That is quite odd. If you could post a save file using Dropbox or Google drive, I could look into it. It might be unrelated to my mod though.

I'm getting the same thing. The game won't complete after hitting next turn. I tried rewinding 5 turns and giving all my shares to the humans. It still got stuck after 289. So then I tried rewinding to turn 265 and buying out a stock exchange as soon as it was available. I got the victory around turn 281 without issue.

So somehow your game is breaking on turn 289 irrespective of the economic victory condition. I don't know why this is happening. The error log seems to suggest the game is getting stuck in some loop. I can't tell whether it is related to the mod. Without the tools the developers have access to, it is difficult to assess the cause of these sorts of things, so I can't always tell why they are occurring. Hopefully it's just a one time thing.

Thanks for the help. Hopefully it is just a one time thing.

In a few multiplayer games now the Darlok and the Trilarian have consistently had exceedingly high research treaty costs (13k BC and up) compared to other races that are all still down in the 100s BC range. This includes when they're controlled by a player and are not ahead in research or anything like that.
