Posted September 12, 201312 yr Im currently working on a fun mod called "The Derpy Pig Mod". It's based on resinresin's Derpy Squid Mod. I spent days on trying to get the mod to work and finally got the following features: -Tools -Dimension -Mobs (One is a WIP) -Blocks -Biome (Used in the dimension) -Portal Block This mod works fine in eclipse, but once i export it to a ZIP and put it into the "mods" folder, whenever i open a world, my minecraft crashes. Here is the console output(It doesnt give me a crash report ): Launcher 1.2.2 (through bootstrap 5) started on windows...
