Calm spirit breaks bear traps
When a survivor steps on a bear trap whilst using Calm spirit, when you down the survivor, the trap looks like it stays open. However the survivor can't step on it anymore and when you (the killer) step on in you don't activate it either, but instead become incredibly slow. You can still pick up the trap though, but I'm not sure you can re-activate it while it is in this state.
I was playing The Trapper on Gas Heaven, the survivor who had Calm spirit and broke the traps was playing as Gabriel Soma. I was playing on PC and in a normal game.
