Updated the mod to the lastest one using this to v4.1.1
After a relaunch the game just crashed

I have enable populateNeighborTable in the mixin.json, sadly with the current lastest version it just crashed on any launch attempts
Using an older version, e.g v4.0.0 works fine

You can easily fix it by using FerriteCore version 4.0.0 or lower!

FerriteCore is no longer compatible with Hydrogen in 1.18.1, since Hydrogen has been officially discontinued by Caffeine/Jelly. I'll keep this issue open as a reminder for myself to add an explicit incompatibility to the fabric.mod.json.
