It seems someone has created another skin with the same crash characteristics of galek_mech. I have galek_mech and I was crashed out, twice. If people can make crash skins at will and give no way for others to get them too, 1.02 will end.
Guy, it is old thread. Anyway, there is already 1.4 patch.
But yeah, there are buggy skins. I'd recommend pure servers
