Here is what I would do:

• Install the BSAs
  
• Redate them to 01-01-2006 (download a tool that can do this)
  
• Rename them to xulTheHeath - whatever they are named now.bsa (this is to load the bsa last)

this will ensure that the game has any missing resources, and that anything else that conflicts with it "overwrite" it.

xul isn't that Unique Landscapes?

Doesn't matter, you have it in your load order.

A BSA can be loaded by any esp, using that ensures that it has low priority (BSAs has priority based on name)

Ok so just drop all the BC BSAs into the data directory renaming them to something last in the alpha list?

Can WB change the date/time? If not what tool?

Renamed both bc meshes and textures bsa's and now the neon sign is gone. No dates were changed.

Now I wonder what mod needs this fixed in...

Now to figure out why my rain is missing.

Over 800 NPCs: Assassins, thieves, pickpockets, bards, pilgrims, alchemists, hunters, adventurers, varied Imperial Forces, barbarians, nightblades, commoners, hired guards, priests and healers, scavengers, tomb raiders, bandits & wizards, fences, infamous villains, heros - these are just some of the new and interesting types of characters you will encounter in TIE. Above all else, this feature is the singlemost visual addition to the vanilla game. All custom made NPCs feature vanilla content and items for their clothing, behaviour, items, and weaponry. Think of it as Morrowind Comes Alive - for Oblivion.]

OBMM can change the date - but only on all BSA files at once. It's under Utilities->Archive Invalidation->Reset BSA Timestamps. They'll all be set to 1/1/2006.

That hired guard you're looking at btw came from BC, not TIE, so TIE has nothing to do with this issue.

Ok. I know TIE webpage made mention of them:
