Here is the report from Form ID finder:
From Mod: 00: Oblivion.esm
Object not found in expected location:
meshes\dungeons\caves\exterior\CEntranceWestWSm02.nif
The other thing that's weird is that the file is present in the path listed (i.e. data\meshes\dungeons\caves\exterior\CEntranceWestWSm02.nif). I can look at it with nifscope. I have Qarl's TP3 and RAEVWD, but neither of them have this file. I have uninstalled a couple of mods, so I don't know if this is a remnant from something I removed. Should I just delete this file?
Here's my mod list:

I also looked at my original Oblivion install, with no mods, and there is no meshes directory at all, so obviously Form ID Finder is a bit confused. I'm surprised actually that Qarl's didn't have something for these rocks, but it doesn't have West Weald. I extracted Qarl's to an independent directory so I could check what files it does install.
