My apologies, but this bug is occuring on 1.51. I'm reporting it anyway simply because there's a fair amount of luck involved in reproducing it, so it might be a while before I can capture it again in a newer version.
I found a planet with ruins, and they're amazing; an intact abandoned colony with 400+ goodies to dig up! (That's not the bug; don't fix that.) Now that I've got some construction units in place digging up something most weeks, I occasionally get an error that I reported last week, the one about not being able to load the Entity Framework library. It only happens when they dig something up, and on those weeks it may happen more than once. I think, but cannot prove, that it only happens if they dig up a deep-space tracking network. Based on this, I suspect that an NPR has dug up some ruins, and that accounts for the occurance I previously reported (though they could also be unrelated.)
However, I noticed an additional detail, which you'll be able to see in the screenshots I'll post. Each time I get this error message, alien components are added to the colony's stockpile. They aren't announced in the log, but you can see them in the screenshots.
Before dismissing the error message:
After dismissing the error message eight times:
I hope that helps narrow it down!
Edit: It just happened again, and it announced that I got a "Jump Point Stabilization Module - 150", and that is indeed what showed up in the stockpile. I suppose the tracking station thing was only confirmation bias after all
