TeslaCoreLib Version: 1.0.15.13
Crashlog (): https://paste.dimdev.org/toxetiteko.mccrash
Note: I only used this version of Industrial Foregoing due to incompatibilities with forge.

Note: This is Minecraft 1.12.2 with forge version 14.23.5.2768.

Redownload the mods, its impossible that its requesting 1.15.2 classes with a 1.12.2 version
