I only recently reactivated my account after few years of inactivity.
For some reason, my Fisherman level decreased from 50 to 4....
Fishing was basically all I did in the end before I cancelled my account....
The rest of the levels seems to be the same, i don t remember tbh. Bard is still 50 a.s.o..

Also I have seem to have lost all my retainers and items, only the ones on my character are left.

Lot more but these are the main issues.
