Paid him 176m to get me 11m fishing experience. Job deadline was to end at Dec. 20th and if he was not able to complete job by then I would get gp ratio back (16:1) for xp not gained + 20% of total transaction (35m). I've got a plethora of discord chat's of small talk/chit chat. He started off doing well then sort of died off. I looked up my account daily to see his progress. Last few days no xp had been gained. Tried to msg him on discord to see what was up. Logged into the account to see that the bank pin had been deleted and some items had been taken/dropped.
