Hey, so I dissolved the ferryman in the cave during the "find the master" quest. I want to gain access to the gargoyle nest and I have the jester badge, but the ferryman is not there. Is the nest locked now or do I have to do something to make him spawn back?

Unfortunately, there is no solution for this as far as I know. The update logs didn't mention anything about this fix and the Redyoshi guide (pinned post) also says you get no reward. The easiest solution is to restart and pick the same choices to reach where you were before.
