Seems to be an issue with the Genetics portion.
I do have the Gendustry mod installed.

Thank you,

Same here. Genetics seems to be causing it.

It's caused by this line attempting to load the current Locale on the server - which in turn calls Minecraft.getMinecraft() on the server, which crashes.

Thanks for the report!
Fixed in the next version.
