I've experienced the same thing.

First time it happened Win 10 had to repair my boot disk.

It seems to happen when I run my latest base which I've played for a good 300+ hours. Normally within an hour of gameplay.

I spent some time exploring the map here the other day and it was quite entertaining.

I noticed that angels ores aren't yet supported, but they spawn regularily if you can make it outside the city

This looks great!

I also play Starsector and I would love the crossover!

I also encounter a similar error in 0.17.3. This happens right after the biters have destroyed the initial base, after the Rebuild the factory objective have appeared. The scenario level caused a non-recoverable error. Please report this error to the scenario author. Error while running event level:...
