Recently i have played a match with Ibanjoebeatdown. He is currently a resident, and have heard rumors about him "hacking" in sg. I did not believe any of them, until i encountered the issue itself. I cannot say for sure whether or not he is hacking, so i will assume it is a bug. What this bug consists of, is an invisible player. It is different than invisibility potions. There is no possible way to see the player, EXCEPT ONE. I discovered that if the player in the glitch/bug (the invisible person) is shooting arrows, you are able to see arrow trails, leading you to the player. There are no sprint particles, potion particles, or any particles at all. Please fix it immediately!
This was happening to me at around this time also for me. One of the users was a person I was teaming with and at dm we couldn't see each other. The next time, it was a person that wasn't even online. (I tried PMing them and /seen and I don't believe he had /v.) I also have optifine. I have not experienced this bug anymore since around wendesday, however.
