Or is this a design....? Seems weird.
If we are four players, and player one for example, interacts with a puzzle, then the other players cannot use it afterwards. They get a broken magnifying glass icon... Meaning all other has to rely on one player to turn stuff or whatever.
This doesn't apply on all puzzles but quite a few so far.

I also met this problem.

Hi Ulcerus. Can you please report where this has happened? Thank you.
