I don’t know if this will help but have you tried un-installing the alpha 5 version and re-installing the newer one. I never weirdly had the issue with the two versions. The error seems to me a files missing or became corrupted, But I could be completely wrong. All I can suggest is to re-install it. But others may be able to assist you more. There is a lot of changes in versions so it could be a un-compatible issue between versions, But again I don’t work for stonehearth nor do I 100% know what the error means, Hope I helped in some way
Update : Sorry Didn’t see the message before mine at the start, Worlds weirdly do glitch out at random points, His response may be more useful than mine sorry again.
