Damn... I could've done something about that. I never had a clue, I was dealing with that ghosting couple. One of them killed 3 traitors out of pure random, and it was all he killed before he died.
As I've said, I never paid attention. The screens look legit, though. So what finally made you decide to file in a complaint (4-6 days later)?
If there are that many traps as you mentionned, then it'll be nearly unplayable. To start playing this map, we'll have to make sure that ALL the regulars know that turning on traps near others as an innocent can be RDM.
That happens a lot to me too. I have no idea if it's the server or my router. Anyway, to fix this you have to be patient and repeatedly try reconnecting until the game finally "Parsing game info..."s or something.
Asking permission to unban him. But yeah, next time don't plant C4's for the lols/getting rid of it. If you still do, set the C4 to 10 mins or something, and camp around and kill whoever defuses it (WARN first).
