Surviors don't pick up the puzzle box first thing
I just got out of a match in which one of the survivors picked up the puzzle box right off and started trying to solve it. The killer found him quickly and put him in a deadly state before he could solve it. Since the killer had the box now all the other survivors became revealed and a chain hunt began making the first part of the match disastrous.
Seriously don't pick it the box too early.
