Keep falling over the floor (Mages Guild Anvil)

[exmate]

I´m only having this problem in the Anvil Mages Guild Hall. I get inside from the main door and all the walls and floor disappear, NPCs fall over the floor too, some tapestry and other fornuture which are still present serves as little island where i can walk and the NPCs too. Doors inside dont appear except for the main door.
Tried 'moveto player' all the NPCs to see if any of them maybe caused it, but so far no clue. Anyone which want to help, feel free to ask any specific question, given that if I write down all the stuff i did, will makes this discussion pretty big.

Are you using any mods?

Disappearing floors in that fashion used to be caused by any ESM editing interior CELLs. It's a bug in the engine that was never fixed. You cannot makes cell edits in ESMs, only in ESPs.

There were some mods that had this problem, but the known cases were fixed as soon as the bug was discovered.

If you have mods that add ESMs, be sure to check if you have the last version of them... and also, if you have ALL the required files activated... it could very well may be that a mod has an ESM/ESP pair and you only have activated the ESM file.

In any case, as Josh asked... It would help to know which mods you are using to be able to help further.

The mods i use through the Oblivion are listed below:
-Unnofficial Oblivion Patch 1.0
-Unnofficial Oblivion DLC Patches 1.0
-Unnofficial Shivering Isles Patch 1.0
-Skip Tutorial 3.0
-Fast Exit 2.2.22410

Note: The bug so far only appears on the Anvil Mages Guild, exclusively on the main hall where the floor and the walls are the only missing structures, I could go to the other rooms of the guild through the 'coc' command and verified no problem in any of them . I verified a tip from other discussion, where it was said to try creating another save and go to the place and see if the bug still occurs; I attest that the bug didn´t happend on this second save, so i conclude that the bug is only occuring on my first character save, not in the game itself.
I´m going to try to avoid going there, maybe it happened before the unnoficial patch install.

It could be that the floor mesh got disabled somehow?

You could try entering this command in the console:

prid 4EFED
enable

4EFED is the FormID of the main floor mesh in Anvil Mages guild, and 'prid' selects that object as active for the console. If it was disabled somehow those commands should re-enable it again.

Here's the area in the Contruction set, just to check we're talking about the same cell:

Well i did what you told me, and the problema persist, but a notice that the problem isn´t that the "4efed" (which is the main hall structure) is not enabled, making a looking aroud of everything i see and verified that the struture (4efed) is MOVED all to bellow and turn left. =/

That's really weird... I cannot think what could possibly have caused that :L *confused scratch*

It has to either be,

1. A mod you loaded at some point that for some reason did that change via script and it persisted on your save-game...
2. You have some extra ESP loading on your loaded order (are you using a Bashed Patch?
maybe the Bashed Patch that's picking a mergeable ESP that's loose on you Data folder and you didn't realized it?)
3. the actual NIF is edited/broken

You could possibly try to load up TES4Edit, lookup that formid, and take note of the static object coordinate values, and then launch the game and adjust it using the console? It might work...

Like this, again, start with
prid 4EFED
then:

setpos x 0
setpos y 0
setpos z 0
setangle x 0
setangle y 0
setangle z 0
(*)

That would help if what's been moved is the actual floor object.

OTOH, it could be that the issue is on the NIF (mesh) asset itself and not the position data on the game.

Look for Data\Meshes\Architecture\Anvil\AnvilMGfirstFloor.NIF in your Data folder and see it's there and if it is, try renaming it like

AnvilMGfirstFloor.NIF.bak

...or something so the game loads the original NIF from inside the BSA.

EDIT:
(*) Using this image as source for the coordinate data, according to Oblivion.esm that's what they should have as values:
