[1.12.2] FML is incompatible with LiteLoader


Recommended Posts

Happened on my modded game when I updated Forge via the Curse Client. Attempted to reproduce using only LiteLoader and Forge successfully.

Full log: https://pastebin.com/KKSceydn

The important bit:

Note that Forge version is compatible.
