Or you could just ask in #zatesting or something.
Some things to note:
A_SetPitch breaks in multiplayer
Firing gets pretty weird sometimes as the client and server may desync
Still can't load folders (crashes upon init)
This is NOT an official release. This is strictly a testing build, the absolute most you should be doing with it is loading some mods with it and playing a level or two.
