This is on FTB Beyond, which is using Psi-r1.0-42
The other day, the server crashed. I had made some progress on leveling shortly before then. When it came back up, I logged in, and found that I was at level 8, when I logged out at level 11. I could continue to do the tutorials and gin levels, but no matter how many I did, it would go back to level 8 every time I logged out.
