Hello, when launching Rubidium with Oculus and C'sWM, the game crashes with the message

The game crashed whilst initializing game
Error: org.spongepowered.asm.mixin.transformer.throwables.MixinTransformerError: An unexpected critical error was encountered
Exit Code: -1

i wish to know the issue, please

Have the same problem here and...
I could add this peculiar line in crashlog, that I belive to be a culprit behind.

[16:46:25] [main/ERROR]: Mixin config rubidium.mixins.json does not specify "minVersion" property

Because previous version is working properly.
I hope this will help.

Update Forge and Rubidium to latest versions.
