I found a bug that soft-locks the game. When you try to do the quest with your mother and the fairies, there's a trigger on the map that doesn't get removed, and you get the same scene again and again as the only path you have to exit the map and go pick the items for the quest is thru a single-block corridor that contains the trigger.
After trying several methods (like loading an older savegame and carrying all the needed items for the quest) and advancing the quest didn't get rid of the trigger, I just edited the map so there's a two-block corridor, and you can skip the trigger.
If you have the same bug, this is not a solution (as the solution requires checking the code of the game), but it allowed me to bypass the problem and keep playing.
The bug is in the Steam version 0.52.2. To apply my fix, replace the file attached with the one in the "www\data" folder.
The trigger is in the block marked in this image. Step on this block only once when you get to that point in the game. Then, to avoid entering the loop, don't step on this block again.
