Costume Weapon bug (disconnect)

[Unknown 12]

Hello all,

I added the costume weapon system in my server, all works good but i have a last bug and I don't know how to solve it.

When I hit with normal weapon + costume weapon all is good, but if I unequip the normal weapon and I hit with just the costume equipped I got disconnected after few seconds. I can see in table log.hack_log the message "Combo". I tried a lot of thing and nothing works, somebody have an idea ?
