When 3 of them are put on the same character the game stops. Had it happen twice (not a common thing to witness).
When you play a trait or attachment on a character that already has the attachment it replaces the old card so you cant have 2 not to say 3. Unless I misunderstood what you said.
Yes, you did. The character drew 3 of the same in a row. The game froze. Never had it happen with other traits. With "I am here for the job" I had it happen twice in a couple of months (actually, I think the last time was early February).
So I was right, you phrased your first post wrong. You should have just said, "My character drew three I'm Here About The Job cards and after attaching each of them the game froze."
