Mod is incompatible with dev environment

[Fabian2611]

Modloader

Forge

Minecraft version

1.20.1

Modloader version

forge 47.4.0

Mod version

1.20.1-1.11.16-forge

Description

The mod does not launch when used as an API in a dev env - no matter whether parchment or official mappings are used. Several mixins fail. Maybe the mixin refmap isn't properly configured?

Steps to reproduce

1. Set up a default Forge 47.4.0 Dev environment
2. Use either parchment or official mappings
3. Add FLAN as a dependency like recommended (with maven.blazing-coop.net maven)
4. ./gradlew runClient
