You have some serious memry leak inside your code. I am on cycle 600, and when i load the map mamry usage was about 2600 MB, after just TWO(2) cycles it rose up to 2800 and it's not stopping, i have it paused right now and it is over 3000 now. I mean, i know that as a company all you care is making money (that is why you're doing dlc after all) but this is literraly a torture now. 3070 now.
Play it with complex enough map, or with save file attached
