This is when I thought things have really gone wrong.The whole problem was...texture path in descr_model_battle didn't have reference to mercenaries.

You can read DMP files with MS Word or even Word Pad.Maybe you will find the clue there to why you get CTD.I still think there some problems with certain rebel units being spawn.

BTW if you CTD again and want to read contains of DMP file,end RTW Dr.Watson (some like ddrwin.exe) in the Task Manager.Otherwise DMP will not be saved
