Hey, everytime I use warp it drops my weapon and flag.
If you have a problem with it contact someone from hexerpage.de, in the hexer mod there was a similar skill and it worked perfectly fine.
Cheers!
Hexer had exactly the same problem. There actually is a way to fix this, but due to Hexer being such a large script (just like ZRPG), server latency was a huge problem. Anyway, I think fixing this could at least be given a shot

(yeah - just check a second after warping whether the player still has his flag/weapon, in case he had one)
