SCP-939 ran up to a checkpoint that I was holding; Notified me about bug relating to one of the checkpoints.
I said something along the lines of "Yeah, I think I know what you're talking about. Sounds like a bug report."
He stopped talking for a bit, I shot him to see a response, seeing none I tranqed him
All of this was taken place in a RP setting during a SCP breach.
At least from my perspective, there was no indication of the area being out of character;
Additionally there being other appropriate ways of contacting staff about a bug.
