I would check out our discord for more help with this error. There is also a prerelease version of RimThreaded 2.x.x that you can check out there as well!

worked really good for a minute, now my game is pausing periodically.
not the actual pause, everything stops moving
edit: reduced threads from 8 to 4, only 4 core computer
edit2: now the game is going, but nothign is moving, uhg

You're using incompatible mods with that version of rimthreaded, either you remove the incompatible mods listed on our wiki from your mod list, or you use the latest preview from our discord.

thank you! is there a maintained shortlist? the discord channel is a bit long and it goes both ways
edit: using this version

Yes, the list you should reference is on the wiki. Seeing that you are using v2.2.19, I definitely encourage you to submit a bug report on discord so we can track this better and resolve. I am hoping to get these kinds of bugs fixed before the 2.x.x release to steam in the next week or two.
