Incomprehensible history with preservation. (The Witcher 3: Wild Hunt)

The situation is this, I have two computers in different places, I play on each from time to time.
Until yesterday everything was great.
The bottom line is that yesterday I took level 31 and completed the Griffin set to the master, launched the game on another computer, level 31 was in place, and the griffin set rolled back 2 updates back, that is, rolled back to the previous launch, but then how I have a level left?
In general, it’s not clear garbage, if anyone has come across, tell me how to treat it)
