Same here. Only in to season 174 and two crashes (freezes, game just stops running). Debug file shows no errors. Only common theme is garbage cleanout followed by ZOC calc. Game dies right after that. Does not appear to be combat related since I;ve had on freeze post combat and one just moving on the map. My rig is Win7 32 bit, so we are covering the system spectrum here. I was also running quite well with the latter betas as well. I also took out older mods just in case.
I hope they can pin it down fast too. I can live with reloading the game, but stable is better.
