I'm trying to make a modpack for me and my friends to play. It worked fine but after updating Artifacts the game would crash on startup. Game would start normally after I remove Artifacts.

Steps to reproduce the behaviour:

1. Update Artifact to the latest version
2. Start Minecraft
3. Game crashes

Game Environment
Please provide details about the game environment, either by crash report/logs or by detailing it below.

• Artifacts: 2.10.1
• Forge: 36.2.5
  (for other relevant mods I understand dependencies if you need anything else lmk)
• ExpandAbility: 2.0.1
• Curios API: 4.0.5.3

There seems to be an issue with mixins which is causing the mod to crash outside of my development environment. I've temporarily archived the file on curseforge as I don't have the time to fix it right now (it's only a minor patch, so it's not really that big of an issue)

Looks like the refmap isn't being added to the compiled jar anymore. My best guess is that this is a side effect of the recent ForgeGradle upgrade.
