I've been reading since yesterday but I didn't see anything about this, if anyone has this problem, please help!

I have a tribal - medieval save where all 5 of my characters got their psylink from genes (natural psylink). They were all level one at the beginning of the save and when they were level two I unlocked abilities for them.But when they became level 3, they lost level as if they were level 2 and their skills were lost.

I looked through my mods a bit and removed the following mods from my list:
- No Backstory - Locked Psycast Paths
- Vanilla Pyscast Expanded Hemosage
- Vanilla Pyscast Expanded Puppeteer

The situation seemed to be resolved immediately, so I continued playing my new save. I played for almost three hours with 3x speed and suddenly all my pawns' direct psylink ability is gone?

I loaded the save from 10 minutes ago and saw that it was still there, I continued from there for a while but the problem of losing all abilities when leveling up at the beginning returned. Why might this happen?

I use medieval and tribal mods, but I don't have any other mods other than the ones I already removed for psycast. (Oh I have sleep medidation mod too!)
