Version 0.0.21 was fine. But after updating to version 0.0.22 I m getting a crash when loading the mods in the beginning. I updated forge to the latest. Im using the java that is shipped with the twitch launcher, java version 51. Not sure if that's the culprit.
Crash report attached:

Try updating many of your mods.

You have a mod that is out of date with it's mixins.

Ooof there are too many mods. Some mods definitely need updating, but everything works find until I add bewitchment.

Having the same issue, but all other mods are their latest edition. Is there a simple way to determine which mods are using the outdated mixins? Or will this be a case of "unload every mod one at a time until it works" as the only method?

EnderIO, try updating that. I see it using mixin.

I tracked it down to VanillaFix. Incompat mixins

That would do it. VanillaFix uses mixins.

Found a simple solution...

This mod will make 2 different versions of Mixin to work

I was having issue with mixin pulling up .7.11 but then plugged in this mod and it fixed it
