I'm around day 200. Just married Liena... game now crashes while moving around on the campaign map every time I load the save file after just a minute or so. Its like it runs out of memory or something... stutters and freezes/unfreezes then finally reaches a state where it can no longer recover. Watching my CPU and GPU usage it doesn't get outside of normal parameters. I'm running a i9 @ 3.60 Ghz, 64GB of RAM and a GeForce RTX 2080... so I know its not my machine running out of resources.
