First, thanks for such a great game! But since my current map reached a certain size, I am suffering from the exact same problems that are indicated by wakkomon (end of month crash). Was the mentioned patch released in the meanwhile? How do I check if the patch was installed on my game? I allready checked on steam (check the installed files).
Some more Information: RAM (DDR III 8 GB) and Processor (Intel I7-4700MQ) usage before and after the Crash not significant over 50% capacitiy.
Map: size Big; About 17k inhabitants, a lot of bus and plenty of train lines, Mods: a lot of rail and bus vehicules.
