Now, you all know Bukkit; the server wrapper that serves it's purpose for the customization of the Minecraft multiplayer experience.
I've found a glitch that may have to do with FORGE instead of BUKKIT, since a vanilla client [and a switch to just optifine only] apparently has no problems. At least for me.
Some plugins like to change the names of the players so as they would appear to their liking; such as colored names to indicate a status. That's the problem. The client won't like it and render the player as invisible. Undetectable. The only possible interactions are chat, commands, and a shot with an arrow, or any ranged weapon for that matter. Also only seems to happen when the said player is respawned; not upon login.
I like my mods, and I do love forge; but this glitch kinda screws it over for me for some servers I play. This can be minor or major, whatever you wish. I only hope for it's fix in the future.
Thanks for reading.

P.S. : I'll quickly make a plugin that does the feature that'll conflict with the client tomorrow and put it here if you want to test it.
