Trimesh floor, walls, and some assets gone for one person

Okay I have a weird one.  I'm editing a world with 6 other people.  The floor, walls, and a few items are gone for just me.  I spawn in and fall.  I can see them move around freely.  I think it's a local issue because they published it, and I have the problem there.  However when I switch to an alt it's fine.  It's just my main character.

I can't seem to clear local cash for worlds, and I can't seem to uninstall worlds to reinstall it...
