I updated Majrusz Library from 6.1.3 to 6.1.7 and Majrusz's Accessories from 1.3.2 to 1.3.3. Now the game crashes on startup. (Latest log: https://pastebin.com/JKsrrWMJ). I think it might be an incompatibility between majrusz and rhino because I get errors like [STDERR]: [Rhino] Failed to get declared methods for net.minecraft.class_310: java.lang.RuntimeException: Mixin transformation of net.minecraft. class_636 failed or [STDERR]: [Rhino] Failed to get declared fields for net.minecraft.class_310: java.lang.RuntimeException: Mixin transformation of net.minecraft.class_636 failed. These do not occur if majrusz mods are disabled.

Hello, thanks for the report, it got fixed with the latest 6.1.8 library release

No problem. Thanks for the great mod and the fast update =)
