However, when putting this on a server, it crashes with the following error:
pw.mods.fml.common.LoaderException: java.lang.NoClassDefFoundError: net/minecraft/client/renderer/entity/RenderBiped
Hopefully this can be easily fixed, because I'd love to be able to include this mod.
P.S. Suggestion: Quantum creepers that on explosion create a single block of quantum stone at their location.
