Mixin Bug

Steps to reproduce

Subject: [Bug Report] Mixin Application Failure with Better Nether on Sinytra Connector 1.21.1

Description:
I am encountering a crash during the mod loading phase while using Sinytra Connector with NeoForge 1.21.1. The crash is explicitly caused by a failing mixin in the "Better Nether" mod.

Report Details:

1. WHO (Affected Mod):

   • Mod Name: Better Nether
   • File Name: better-nether-21.0.11.jar
   • Environment: NeoForge 1.21.1 + Sinytra Connector 2.0.0-beta.12

2. WHEN (Occurrence):

   • The crash occurs during the "Early Mod Setup" phase, specifically when Sinytra Connector performs the mixin compatibility check/safeguard verification.

3. WHERE (Code Path):

   • Target Class: MushroomMixin
   • Target Method: #canStay
   • Exception: net.neoforged.neoforge.logging.CrashReportExtender$ModLoadingCrashException

4. WHAT (Error Message):
   The log reports: "Mod file better-nether-21.0.11.jar has failing mixins: - MushroomMixin#canStay"
   It triggers the Connector's "MixinTransformSafeguard" causing a hard crash.

5. WHY (Root Cause):
   It appears that the mapping or injection point for the MushroomMixin#canStay method in Better Nether is incompatible with the NeoForge 1.21.1 runtime environment provided by Sinytra Connector.

6. HOW (To Reproduce):

   1. Install Minecraft 1.21.1 with NeoForge 21.1.216.
   2. Install Sinytra Connector 2.0.0-beta.12.
   3. Add better-nether-21.0.11.jar (and its dependency bclib).
   4. Launch the game.
   5. Observe the crash during the loading screen.
