Looked into this one closely. The fame loss itself is authentic: in the real v83 data a few quests take fame away. 3069 and 3071 give -2 fame, and 3071 gives no EXP at all in any version. 4930 and 4937 give -5 fame along with their EXP. So 'gave -2 fame instead of exp' matches v83 for 3071. What WAS broken is fixed and live now: the reward screen printed '+-2 Fame', our engine sometimes skipped negative fame, 4930 and 4937 had lost their -5, and quest fame now survives a relog correctly. If the quest you did was something other than 3069 or 3071, reply with its name and I'll check that one specifically.
