Lots of fighters causing tactical combat crashes

Stock 171, BM1.14A
I have had 3 different tactiacl battles using between 100-200 fighter along with about 15 combat ships where the program either freezes or generates an error and crashes just as I complete the task of killing the enemy combat units.

I hope Stock 174 and BM 1.14B don't trash my current game. I like the fighter launch fix but I still wait for the supply/ordnance fix.
