@Share doesn't save values for pseudo mixins on Neoforge

[kikugie]

The exact mixin in question: https://github.com/kikugie/elytra-trims/blob/kotlin/src/main/java/dev/kikugie/elytratrims/mixin/compat/render/ElytraSlotMixin.java

Building the mod without the ElytraSlot jar in the classpath results in a broken mixin, where the @Share value is not written.
With ElytraSlot added by modCompileOnly and no changes to the mixin class, the built mixin works.
This issue is exclusive to Neoforge from my testing, as the same mixin works fine on Fabric.

Can you send the exported target class with the "broken" mixin?

Try explicitly specifying the full lambda descriptor in your mixin
