A nice feature to have would be able to easily copy the debug text from an error like this. I was unable to select/highlight the text in-game so I had to post a screenshot.
Looks like your machine is out of memory: OutOfMemoryException: Out of memory (open the log files that you shared to see it). We will try to make this issue reporting better.
Weird I just tried again and the game only allocated another 400MB before giving the same error. I have 32GB of ram and I never saw more than 14GB being used with other stuff open. Is there a way to allocate more to the game?
I think I found out what was causing the issue. I had set a environment variable for Mono MONO_GC_PARAMS where I changed the nursery-size and a couple of other values. I removed the variable and rebooted and it loaded up a save I had from a while ago. Im assuming that one of the params I had set (probably running the GC after some ms delay) didnt like the game loading. Ill close this issue out.
