The save that I attached in the original post is an autosave at the start of a terror mission. If you take the hunter north, you will run into a group of Androns in the middle of the street. If you blast them so that the shot damages 3 or more, the game sometimes crashes to desktop. Sometimes, it CTD's on the next turn when another Andron walks over the charred tiles. I followed the instructions above with the DEP and C++ package install, and that seem to have helped with the explosion bugs.
Last night, however, I had a pretty consisted CTD when a Sebillian was using an elevator to come to ground level in a cruiser crash mission. The only way around that was to push the action upstairs ASAP so that he never had to come down.
I will check later to see if I have that save as well.
