I patched the server and restarted it. The weird characters are fixed when you switch in a poke. They are now gender symbols like they are supposed to be.
Also fixed Mountaineer. It was originally implemented as full Rock immunity for the first turn Syclant switched in. Even if it switched in "simultaneously" with an opponent. So, if a poke exploded and the next poke tried to use a rock move on the first turn against an opposing Syclant, Syclant would still be immune. Now, it is only immune if it switches into a opponent's attack.
Keep reporting bugs and I'll keep fixing them.
