[Survival & creative bug Multieplayer]

The commandblock command /xp [give,remove,set] doesn't work, in singleplayer the command /xp -3L @p does work, but in multieplayer is doesn't work.

better to say all commands with /xp doesn't work with the commandblock, because it is a bug in multieplayer. in single player it works only there, but not in multieplayer what is very annoying to make maps.

That is the bug that i want to report.

I hope that it will be fixed in 1.6
