IceWall crash server

[3TAJIOH]

When I attack IceWalls with normal attack, server crashes. But I can attack it with skills.

The character does not attack at a great distance, he stops short of 5 cells. And when I come close to the IceWalls and press the attack, the server crashes. When attack IceWalls with Sniper, server crashes too.

Compile your server with debugging symbols.

Start your server with gdb.

Wait for crash.

Get the backtrace.

Share the backtrace here. 

[Normynator]

gdb ./map-server
