Looks very similar to #93, but the difference here is that the wizard is directly targeting the mob grinder rather than it just being a revenge effect. Thing is, the targeting methods are part of vanilla and therefore Forge fake players shouldn't be affected. I think there's a fix I can do, but I'm confused as to why my code specifically would cause this error. Thanks for reporting.

Fixed in the 4.2.0 release.
