Consistent CTD whenever I try to move from Area 1 to Area 2 of Lillipa Desert maps.

I can load into Lillipa Desert missions just fine but every time I try to move from Area 1 to Area 2 of ANY mission on a Lillipa Desert map I see the loading screen pop up, I see it load a little and then the game just ends itself and kicks me to my desktop. No errors given.
File checking doesn't result in any downloads of missing files.

Two rounds of verifying game files later, still with no noticeable downloading of missing files and the problem has disappeared.
