BGT Megamod- Walkable regions all messed up in Waukeen's Promanade

Hello,

I'm running a BGT megamod and for some reason my walkable regions are all messed up but only in Waukeen's promanade. Right now I cannot enter a few modded shops but more importantly, I can't reach or find exits on the maps. Is there a way to fix the in DLTCEP? I thought it might be less of a hassle than reinstalling/troubleshooting the bug. Attached is my area file if it's of any use.

Thanks!
