After completing the first Resistance Op of my new campaign, when I clicked the continue button, the game crashed before transitioning to the skyranger.

Disabling this mod fixed the problem. I suspect it has something to do with this mod's use of the resistance firearms pack, which other users report caused similar crashes.

I had completed Gatecrasher and the first Guerrilla Op, so it's not all missions.
(This Resistance Op was my first mission with Lost—or any third party, for that matter. Maybe that's relevant?)

Thank you for making so many cool mods!
