Problem with packet

[Onnyx]

Hello
I don't find the solution for this packet error :
When I change map (with @go/@warp or with warp), I''m disconnected to my server and I've this error :
[Warning]: clif_parse: Received unsupported packet (packet "$packet", 4 bytes received), disconnecting session #3.

But the $packet change all time :

0x8e22

0x860d

0x4019

0xada5

0x179e

...

 

Why >< ?
