Mod crashes when running on server

[dngoodman]

Just added this mod to my pack. Tested it on the client side and it seems like everything's fine. However, when starting my server I get the following error: net.minecraftforge.fml.common.LoaderException: java.lang.NoClassDefFoundError: net/minecraft/client/audio/SoundManager Looks like it's trying to load the sound manager and that's why it's failing. The full crash report is below:

[MoonManModding]

Thanks for reporting this! Unfortunately I haven't had a chance to test/fix the mod on a dedicated server yet. I'll put a version out today which will hopefully resolve it.

[MoonManModding]

This should be fixed in 1.1.3-beta although I won't be able to test it more rigorously until later.

If you have any problems please let me know.

Thanks again

[danngoodman]

I'll try it out when I get an opportunity in a few hours. Thanks!

[dngoodman]

Tested it out and it now loads on the server. Thanks! I'm gonna close this now.
