Problems with zp?

Well, tonight I was searching for new servers and found one that I actually liked and had good ping in there! There, I remembered that eeverytime I play with zp, there's a message that says ''Say !mutate zp_off to disable zp'' and I opened console and copied that (Mutate zp_off). nothing happened, and I wasn't really concerned. However, after adding that server to fav's list, I went to Siege server. Map was Niven, but-
The most terrible thing was happening...

ZP WASN'T WORKING!!!!!!!!!

I know zp only works on Instant-Shot weapons (Enforcer, Shock and Sniper) and only ''removes'' lag on their primary fire, and that was EXACTLY what was missing! Enforcer Primary Shot SOUNDED like a shot (Secondary shot worked okay), but no bullet nor ammo gone! Same happened with Shock and Sniper (Shock: Shock beam went out, but no laser to make combo. Sniper: Zoom was ON, but bullets OFF).

I realized two minutes later that it probably was the ''mutate zp_off'' command, so I went to console and copied ''mutate zp_on''. Sure enough, It said ''ZeroPing is working again'' or something like that; but it was NOT working!!

Bio, Shock 2nd shot, Pulse, Ripper, Minigun, Flak, Rockets and Sniper's zoom aka NON-zp weapons/shots worked PERFECTLY!

So, then I did the reconnect thing, and still didn't work!
Closed UT, started again, enetered again and STILL didn't work!

If someone can help me with this, I'd really appreciate it!!
