I'm currently replaying Origins and every time I've done the forest stream encounter with the multiple quinari mercenaries the game constantly crashes. I've lowered the graphical settings, turned off frame buffer effects, ran the 4GB patch, turned on compatibility mode, and have vsync on and it continuously crashes. My mod list is:
Skip the Fade
Grey Warden Armors
Extra Dog Slot
dialogue tweaks
Morrigan Restoration Patch
Quinari Update
Icons Project
Advanced Tactics
Improved Atmosphere
Pineapple's Vibrant Colors
More Hairstyles
Unobtainable Item Fix

Is there anything I can do other than unistall and reinstall at this point?

try it without the mods
