Taimanin Collection: Battle Arena: Puzzle Pieces fused completely wrong, Game Breaking [Bug]

I can't beat these two Puzzle Minigames, as the merged Pieces have a chance to detach from each other, but remain linked in a way, by some freak chance, rendering these Puzzles unbeatable since I can't move them back to the correct positions. In this state, they are even able to override other Pieces underneath, but that doesn't matter as, again, it was unbeatable when it started happening.

This happened twice on the same day here. Too bad I did not showed it in real time when the Pieces detached, but I don't like recording all gameplay 24/7, but you can't deny this isn't how it's supposed to work.
