The mod was working fine when i added to my Modpack, then i went underground and it keeps crashing. I tried removing AmbientSounds 3 to solve it, but no luck.

Here's the log: https://pastebin.com/K50Np5zH

I believe this to be a dupe of #1 . It looks like there is a blockstate that was registered after Environs scanned the registry.

Allright. I just read the thread and i'll try to install the test version you made to see if it solves. If not, i'll try every individual mod with Environs to find any incompatibilities. Thanks for the reply anyway.

Yup. I've been playing for 15 minutes and no crashes (i was getting crashes every 1 minute). You, sir, are a genious.
I'll leave the thread open in case it crashes again till tomorrow, but anyway, thanks for the fix.

Pushed release build 0.1.0.0 to CurseForge
