I've seen this issue before, but this is the first time I was able to get a clip for proof. The first time I've seen it was the Nic Cage PTB. It's literally just a reasonless obsession swap. (Mikaela (not obsession) gets hit and a player in a torment cage becomes the obsession). In this clip its The Executioner using:…
After another players blast mine is used, a new blast mine is applied, the blast mine charge is consumed, but the second blast mine does not stun or blind the killer. Wiretap still being on the gen is my only though for why the second blast mine doesn't work, but is consumed.
