I've noticed I am crashing pretty frequently and often in the same area inside The Fort. I cannot for the life of me figure out what could be causing this so I am asking here...

Just guessing have you tried disabling the patch or chem mod? If I recall right, the fort has an npc that tries to remove weapons and chems. As for the patch, not sure whats built into it

Anyhow try those two! If that doesnt work, maby disable everything else and see if that fixes it? If it does, then its some other mod, if you still crash, then its probably a mod that altered a variable that saved with the game.

I used this mod before without any issues. I will try it though and see. What is the patch you are referring to?

You have Compiled Patch.esp listed in your order. No idea whats inside it, so it may or may not be an issue

Ah, that is a bunch of bug fix patches.
