It can't be events, I've experienced this twice in my server and my server was passworded, there was nobody but I and Negative, no more bricks than mine, and bew, the face appears, playertype changes and I see Fungus "talking" in the chat (I heard no chat sound even the mod was on)
It's just impossible to be events, there MUST be more than just events, because just like I said, there was nobody but me and Negative, and it can't be Negative unless Fungus is very good at finnish and has known me for a one year. If it was events, Fungus should have joined the server, planted a brick/used a brick of someone who's trust he has and put events on it. Everything I just said, was impossible in the situation it happened.
+There are no such an events to do such a things for everyone without a mini-game in my server.
