Additional/Glitched Experience Bar

Invalid unless reproducable in vanilla.

Why would this be invalid if it is obviously a graphical issue client-side?

"Though the experience was set using a Bukkit Plugin" > Bukkit is a modification.
Give us steps to reproduce in Vanilla, and we can properly review it.

Bukkit is a server-mod, not client side. I'm reporting a client side issue.

server sends rendering data to the client, the client just does what the server says
like the hives hide and seek shows a block instead of a player

Sorry, FVbico seems to be spouting nonsense again. The server sends no actual rendering data to the client whatsoever, or we would all see Bukkit servers creating completely custom looks on servers and client-side resourcepacks wouldn't work on multiplayer.

what do you mean by again?
but even it that's not the case, you have to show that it works in vallina minecraft

Please give us a way to replicate in Vanilla Minecraft, without any 3rd pary tools used.

FVbico, correct me if I'm wrong, but the server sending packets for rendering entities is completely different from the client displaying the exp bar. The server can't tell the client, "add another experience bar off-centered", this is a graphical bug client-side, the experiencing is displayed properly until level 101 is reached. Then the 101->102 bar is displayed off centered, and upon reaching 102, the bar is correct again.

Nevertheless, the issue was spotted on our side, though it is very silly that the client would render additional experience bars if given a experience percentage over 100.
