No no savegame not the reason of it
I restart, renamed, resaved old (1.56) and new (1.60) missions - but crash
And I should tell, that all old missions (1.56) and their old savegame in standard Takistan, Zargabad, Desert perfectly work on 1.60!
I have lost Tora Bora and ClAfgan :(
Yesterday I have tried Hazar-Kot island. My first computer with 1.56 perfectly played missions on this island. My second computer 1.60 - crashed
