I played against a huntress and was at the hook, when the last gen was done. Then someone saved me but adrenalin was not getting activated. It was on the saloon map in i got downed by a hatched but i dont know what addons the killer used. Still strange bug.
Yeah i had a round with a Hillbilly that had tinkerer + apex muffler but it was not active and still his chainsaw was silent all the time.
