The Eating Animations mod requires GroovyModLoader (GML) as a dependency, but that mod is incompatible with Eureka/VS2 as it causes a crash on startup. The Developers of Groovy don't seem to be very active/motivated to fix this issue as it has been reported over a year ago. GroovyMC/GroovyModLoader#30
Please either move away from Groovy or apply a fix via the Eating Animations mod.
