Hi,
Just a small bump,
I tryed to fix this issue today but still could not make it work...
I am not sure if the description really help to understand the problem,
In case, I attached the scene, as a prefab.
The mechanic work if each puzzle piece, have a FSM that detect a trigger enter.
But I wanted to have this script in a single GO "_gameMechanic" and have a get owner to each single puzzle piece... so it is more clean.
Now I am not sure it is doable.
