Alchemist's Ring Bug
If you hit somebody with a lethal rush while running Alchemist's Ring and try to immediately rush again with the tokens that you got from the ring, it'll stun you immediately.
Hit survivor with lethal rush and Alchemist's Ring and then immediately perform another rush after the first stun. This should result in a second stun immediately after pressing the rush button.
Haven't been able to reproduce it in a custom game, not exactly sure why. I can't test it anymore in public games because I'm out of rings. I'll update this if I manage to reproduce it.
