Enimies stuck on wall cant kill or get to them

[CarnageAce]

my Out post got attacked, enemies walked onto my wall from outside in an area that cant be walked on. My squad could target them but invisible barrier stopped bolts hitting them, I decided to delete the wall they stood on they fell to ground got shot an died, I tried to pick up materials, a spot light was floating in the air, tried to dismantle and it crashed.

repeatable, second crash file added . Also behind this wall are materials that can not be picked up, an auto engineer will go there to pick them up ignoring other stuff if it he needs the materials and just stand there until materials are put in his pack or is forced to do something else.

I have the autosave just before the crash, but the zip file is to large to add 35,138k, let me know if you want the save and how to send it
