Installed the newly updated mod, and game crashes on startup/load.
Ive attached the crash report on pastebin.

This looks like a weird interaction with Oh The Biomes You'll Go and Sodium Reforged (Halogen) and have nothing to do with JAOPCA, please check if crash persists if JAOPCA is removed

Crash does not persist if i remove latest version of jaopca. only occurs with latest version. crash goes away also if i downgrade jaopca to JAOPCA-1.16.5-3.4.0.12

Unable to recreate crash with JAOPCA, Tinkers' Construct, Oh The Biomes You'll Go, and Halogen.

Another crash log from just now, did the same test, updated to new JAOPCA and then crashed. Reverted to old JAOPCA and no problems.
