Can Mods cause Beregost bug?

Hey guys, I am currently getting the Beregost bug on my games.

I explored Beregost - did my raiding, collected quests, ect. Left, created a separate save file as I have been troubleshooting this for awhile, exited the game, started game and verified that fresh save could re-enter Beregost. Then reloaded that save and went from there.

So I continued, explored nashkel and nashkel mines outlying area, and now I am getting a Beregost bug.

I read some old old posts about the door to the jovial juggler causing the bug if it was left open. But that isn't linear with what I've been seeing as I have been able to go back with it open.

This has happened three times now... where I was watching my saves, went through, happened again.

I am using SCS, BG2Tweaks and BG1NPC mods.

Is there a chance the mods may have something to do with this? I can't really get around it because it's happening in each playthrough. I have at least been smart enough to make so many save files this time around that I have not lost my game yet. I have a file that will load Beregost - but it's only a matter of time. It is not very immersive when I have to paranoid load-save-check every time I am at the edge of a map.

I haven't even made it into the Nashkel Mines yet without stumbling into this =(

Sigh. This game is amazing. Should I just uninstall all the dang mods and play??
