Game crash's all the time and is unplayable. It normal takes 200+ turn before it goes completely but can start crashing at 70+ turns. Once it starts with in about 10 turn it will always crash at turn after loading from save.
I had no problems playing it on 1.3 but the crashing started at 1.4
System is as:
Core i5 3570
16 GB Ram
Have tied it on Windows 7 and 8.1 and older Nivdia driver, crashing always the same.
I also deleted all steam file's and save file's and download the whole game a fresh, still crashing.
There is a growing number of people on the Steam forum with the same problem.
Great game, please fix it as soon as possible.
