It's not working with the latest versions of WAILAPlugins.

Using Magical Crops (release) v1.7.10_0.1
Worth to mention that I also found this in the fml-client-latest.log file.

I can only support one version of Magical Crops and right now that is the 4.0 BETA version.

Alright, I figured that that's the case, it's just that I didn't see anything in the changelogs. Maybe I missed it.
Thanks for the reply!
