[Help] Some strange BUG, crashing GameServer.

[motanu]

Well there is a strange bug, that players are now exploiting, in order to crash the gameserver.

So far so good, I know that, they are trying to teleport from Donwhang to Jangan/Hotan with Job Horse on, the problem is that there is no Error in any log. After some investigation (OllyDbg) I figured it crashes during the COS State Change function in the GameServer, although I was unable to fix it.

Thank you,

How do they teleport if it isnt possible to teleport with a jobpet on?

It is like the bug when thiefs can enter transports inside cities.

summon-terminate-summon-terminate-summon-terminate-summon and when the attacker reach a bit of game delay (becaues of light DDoS attack or something) teleporting btw towns while ridding trade transport is posible but the GameServer stop working making server crash.

As far as I know, all city teleports are vulnerable.

Do you have any idea how I can protect myself from this ?

If you got the address, you can tweek the GameServer to avoid the "stop working" problem.

Or you can disable all main city teleports.

The first one is the recommended, but you have to know where to look, as disabling all main city teleports will end in a "strange" gameplay.
