I've got a problem. I can hardly play 6 cycles in a row. After each automatic saving after a cycle, the game gets more laggy until my PC completely freezes. After some minutes the game crashes to desktop (or my OS kills it, I don't know) without any crash report or so. It seems that the RAM usage is about 99% (the total amount is 7.6 GB).
What could it be?
Play 6 cycles in a row with the autosave-feature turned on.
