Hi, I am experiencing a startup crash with Nostalgic Tweaks when BetterNether (https://www.curseforge.com/minecraft/mc-mods/betternether) is installed. I have included two different crash reports, as the game displayed a crash report for both BetterNether and Nostalgic Tweaks, and they seem to be related.

Nostalgic Tweaks:

BetterNether:

Thank you for submitting this! I am currently focused on fixing crashes and compatibility issues for the next update so the hope is to have this resolved in a update coming very soon. 👍

This issue is now fixed in v1.0.3.
