While I was playing on the Polus map as Impostor I was chasing someone and killed them, I don't know what exactly happened but instead of them disappearing and turning into a ghost they survived somehow but their dead body was still there, the body was reported and the guy I killed was still able to chat as if they were alive and told them it was me. I just wanted to bring this to your attention.
Also, I know someone has reported this glitch as well but in Skeld even when you can't see inside a room you can see the vent open animation when the Impostor vents.
