Game freeze and knowledge point disappear

The game froze while I was finishing it, and I restarted it, my knowledge points disappeared.
677 knowledge points have been used,but nothing can be built.
please let me know how to fix it.

Try resetting the points with admin mode or potion. Maybe that will help?

I was in a similar situation. How about using a power shard multiple times to unlock alchemical knowledge?
I hope your magic tab hasn’t disappeared…
