Problem in Warfare dev

Warfare mod is not a too difficult mod to code, but i have a very strangly bug (sushi tee saw it).
I searched a lot of time without find anything.
So i need your help devs.

I would like draw some flags, like in domination mod, to represent nodes and generators.
But when I send more than 3 flags (snap(int) function whith a NETOBJ_FLAG), the client lag and totally freeze.
You can kill you and speak anyway, because the server still works well, but you can't move and the client says "prediction time reset".

I hope you can help me.

PS : For those who are waiting Warfare, when this bug will be fixed, i will can code very fast don't worry .
