Any mod that uses methods in ModLoader.class crashes the server

knarf2011 · February 18, 2013

I had a mod(http://www.planetminecraft.com/mod/burning-war-mod-forge/) that I made, and was crashing the server, but not the client. The crash report seemed to point to the cause being related to ModLoader.class, possibly missuse of it.

I tried re-wording the code in my main mod class file, but nothing seemed to work. So I tried the same thing with a popular mod that uses ModLoader.class (http://www.planetminecraft.com/mod/146gem-mod-new-armor-new-tools-new-food-new-blocks/), and got a similar crash report, this time when apparently using ModLoader.class to add acheivments.
