Trying to solve these crashes. I'm quite stumped as to why they are happening. No errorlog has popped up yet. The world only crashes when it's small, medium, or large. The larger the world, the sooner it crashes. Smaller and tiny worlds gen fine. Which just adds to the frustration. What happens in larger worlds that doesn't happen in smaller worlds?

Large : 3 years
Medium : 10-30 years
Small : 60-80 years

I suspect it might have something to do with entities changing. As the crashes only happen once everything is moving. Specifically something wrong with the civilizations. Other oddities, setting everything to very low except for time will make the world gen fine.

And while I am typing this I just genned a medium region to the year 103 with no crashes. Just did again to the year 100, so it's not an anomaly.

The Medium island crashed at year 50 and the second one at year 2...

There must be some link here. Population problems perhaps? They can't expand anymore because they are no longer starving off in the latest version? I'll continue to test.

Perhaps it's an animal, which would explain why there are more crashes on ocean worlds. But what animal could do such a thing?
