IGN: Berleezy_ Where Bug Occurs: So far it's been on Creative and Sg. Description: So I first noticed a couple days ago on sg when I has playing a match. I was going against 3 players teaming so I ran from them. When I stopped I looked around to look for them and saw nobody around. A few seconds later I was being hit and saw nobody around me but I was being killed. Right after I was killed and in spectator mode (that the correct name or no?) I noticed the same 3 teamers were around me and getting all my stuff. But they weren't invis. So I just thought my game was messed up so I just relogged. I went to another server to see if it was going to happen again and it didn't. Now today I was online at creative and noticed my self invis in 3rd person but I was visible to other players which was strange. That's as much as I know so far. (By the way those teamers in sg weren't hacking if you think they were. I watched them until the end of the match and they were playing legit.) I know this map not be the best description but I did my best.
I'm not sure if the server can really fix a bug like this; it could be caused by many things. I've seen tons of different bugs on the minecraft bug-tracker related invisible players/entities. You'd have to figure out what specifically is causing it and what the bug actually effects. Basically what I'm trying to say is that lot's more detail and investigation would have to go into this bug to really figure everything out.
It is with optifine i think, as the same thing happens with me. Players randomly disappear, but they don't when i turn off optifine
