Can't finish "Saved by the bell"

[sea.dart]

Got the quest "Saved by the bell" where you ring the bells to match the theme song. I finished the quest and got the treasure, but the mission won't mark as completed. If I redo mission the loot box stops already opened. Is there a way I can force complete or force drop the mission so I can complete it? On PC.

Got into the same situation yesterday. Installing updates did not help. Restarting the game did not help either: everytime I complete the task I get the box, but quest does not become complete.

I think I may have played with the bells before I got the quest. That may have messed up the quest. I did see a post on Steam about a save game editor, but I wasn't up to messing with it.

Unfortunately, I did not play with the bells before the quest. Will wait some time for developers to fix it and then will look for the editor. This quest is the last one to get 100% completion...
