After forfeiting the quest, my puzzle board still stays in my inventory and I can't drop it nor can I open it up to finish up my quest. This bug is similar to https://royals.ms/forum/threads/cassandra-jigsaw-puzzle-quest-bugged.142397/ The author of that thread told me to write a new post to notify a GM and they will forcibly remove the puzzle board from my inventory and that would fix the problem. Do help me out any GMs reading this!
