How does one install the mod on a server?

I am running the latest version (1.3) and when running it on a server it gives me this error:

Caused by: java.lang.NoClassDefFoundError: net/minecraft/client/renderer/BufferBuilder

which means it's a client only mod (as gathered by the forums).

lol oops should probably close this now

Confirmed. Seeing this crash on server start after upgrading from 1.2 to 1.3

I think this might be related to #19 because I got it when I was on version 1.3.

This. I have this also. :V

I managed to fix it, in the preInit function inside the MonkMod.java, move line 84 above line 98 (MonkTextures.init();)

That fixed it for me
