No explosions, emitters...

[Chefzor]

So i was building, and then a dude joined my server and spawned, then he started spamming me, and i noticed, that there is no print emitter. So i set an emitter on a brick, and it doesnt appear.
I guess its some broken addon bugging me, because the dood saw them, and i didnt.
-------
So anyone who is reading this topic, i ask for your help... What addons could it be, that bug them?
In advance, thanks :D

There is a bug where particle emitters stop:

----	This is due to a fix for a crash where particles would keep going after you disconnected and do bad things.  It is triggering when it shouldn't.  If you can duplicate this problem consistently I would like to know how.
