Regardless if he said to stop or not, I don't agree with that behavior. But I do understand if you're "messing around," it's fine as long you two didn't affect the other players on. If you're merely screwing around, fine. Have at it. @xGTim you said you told him to stop over team speak. There's no way to prove it either way, it's merely your word against his. So, focusing on the actions themselves. I'll talk to Mega and Hidingmaster later about this.
@WhyJewMad; anything to say for your case? (TS - namely)
Edit: If Tim never said anything, I'd -1, this entire situation seems completely unneeded. Two conflicting stories by two staff members.
