Now this may just be my stupidity but whenever I load this mod on my server it crashes with "java.lang.RuntimeException: Attempted to load class net/spellcraftgaming/rpghud/main/ModRPGHud for invalid dist DEDICATED_SERVER" and the crashlog is here, this is an fml crash

the same fail here, some news?

well. this is not really an issue or problem on my end.
The mod is entirely client-side, meaning it should not be installed on a server (it works regardless).
Just remove it from the server-side mods folder and you're good.
