Forge:14.23.5.2847
Mekanism:1.12.2-9.8.3.390
Other relevant version:

Not sure what happened as it seems like something failed in mod construction (which is a forge process), going ahead and closing this as it is likely an interaction with some mod (or core mod), and the entire mod construction process got rewritten when forge underwent a rewrite from 1.12->1.13/1.14 so I don't believe this should ever be able to happen anymore in 1.15.
