Hello,

Recently I found a bug, that happens every time I'm either breaking a metin and then get poison from some monster that came from the metin or even a stand alone monster... (we found this bug on metin 8009 (monsters from desert, v2), the monsters give poison and the server crash)

Sometimes when I teleport to other maps (if the map is on another core) the server crashs (this if poison is given by a player and not a monster)

This is the debug:

root@sv1:/usr/home/game/share/bin # lldb game -c game.core
(lldb) target create "game" --core "game.core"
Core file '/usr/home/game/share/bin/game.core' (i386) was loaded.

    }
}

Is anyone able to help me?

Thank you all
