Hey guys!

Recently I've started a custom modpack with some friends (first one I've done so far) and for some reason Builcraftlib is loaded , constructed and errored (LCE status). If i scroll down a bit I also get the message:

" net.minecraftforge.fml.common.LoaderExceptionModCrash: Caught exception from BuildCraft Lib (buildcraftlib)
Caused by: java.lang.NoSuchFieldError: ON "

I tried to see if it overlaps with another mod but I'm kinda clueless to be fair...
Here's the full error: https://pastebin.com/KhALHp1c

To mention, forge version that I'm using is (14.23.5.2836), Buildcraft version (buildcraft-all-7.99.24.2), Minecraft version (1.12.2).

Thanks for the help!

This is caused by one of your mods including an older version of the buildcraft/api/tiles/IControllable$Mode.class files, which is being loaded instead of the newer version. Unfortunately I'm not sure how you can actually find this out, other than opening each jar file in turn to see if it contains that file.

Hey, thanks for the response!
From what I understand, should I uninstall buildcraft and install every jar file that make buildcraft as a whole? (api/builders/compat/etc...)

Oh wait lol, I'm dumb, now I understand xD

@AlexIIL issue is fixed, problem was from Engineer's Toolbox mod.
Thanks for reaching out!
