Ryzom Crystallize glitch? (spell cast?)

[swe999]

You only see the person reacting on your screen. They don't see anything except you doing the spell animation.
If you want to see it in action heal bomb some people, then crystallize

Hey guys I get this glitch while crystallizing. click on player and then right click crystallize then I cast a spell at target (does no damage but person reacts to it). Then it started to glitch on me. Well I dont know if it is a glitch or not. Maybe it looks different on guys? Link http://www.geocities.com/thasor
