Profession Rollback for the 4th time.

I don't know why this happens because I never use the puff towers or anything at Windia Farms. This is the fourth time this has happened and it's a really annoying hurdle in the way of me crafting my Endairon Equips because I have to "Re-Learn" the crafting skills and start from square one every time.
Waiting for your reply Thanks in advance.
