I've just re-installed Oblivion and all my many mods (including FCOM). All's running fine except I've hit a bug I've not seen before:
First one shop in the IC Market District (Divine Elegance) and now two (The Best Defense) have started staying shut during the day. If I go back to earlier saves they're opening normally, so I'm guessing it's not a mod conflict - and anyway, I've added no new mods since before the problem started.
If I unlock the doors and go in, the owners are missing (well, only Mario Rufus is missing in The Best Defense). Knowing a little about the infamous bug created by the Frostcrag Tower DLC mod, I guessed that the NPC's have got misplaced by the game so can't go through their shop-opening routine. But if I use their Ref ID's to move them to the player, they just wander off into the Imperial City.
I wouldn't worry too much - I could just go back to an earlier save before the problem arose - but since the bug has spread from one to two shops, I'm worried it will reappear and spread further.
Has anyone seen this bug before and have any idea how to fix it? For example, how can I get the shop-owner NPC to switch from wander mode to shop-running mode?
Any help would be greatly appreciated.
