Uhm, so .. THe Clay Man quest is bugged, weirdly.
Here is what happened in chronological order for the purpose of figuring out the bug!
- Someone else starts this quest.
- Someone else gets the clay from the patches
- I start the quest
- I get the clay from the patches
- Someone else finishes the quest meanwhile, and my journal updates along (at least it claims so, nothing changes)
- I give back my clay - quest closes, but I get FLAGGED FOR CHEATING.

It happened to me earlier, that if two people took this quest together, when the first one gave back the clay to close the quest, the second one, eventhough the quest was still active in the journal, couldn't get anything from the clay patches, as if never starting the Q.
P.S. Had a very similar situation with the Physician quest a few times, if two people took the quest at the same time, then when the first one closed it, it auto-closed for the 2nd one too.
Many of the fed-ex quests do this. The water leak one does it I know as well.
All this should be fixed next reset.
