BuildCraft Crash


Recommended Posts

Caused by: java.lang.NoClassDefFoundError: buildcraft/api/fuels/IronEngineFuel

    at mekanism.generators.common.MekanismGenerators.postInit(MekanismGenerators.java:77)


Mekanism is trying to use a class from BuildCraft's API that doesn't exist. Update both mods to their latest versions.


Where did you get that copy of BuildCraft from? It doesn't look like it was downloaded from the official site.

Please don't PM me to ask for help. Asking your question in a public thread preserves it for people who are having the same problem in the future.
