Same thing happening on 1.10.2?

CoroSauce has not commented on the patch but I am using it in a production environment and it works. You should be able to copy the same code into the 1.10.2 version and compile it for yourself, unless CoroSauce decides to apply this patch.

A dumb bug on my part now fixed for mc 1.10.2, not sure if will fix in 1.7.10, you can just disable speed boosted mobs in config, see #12 for more info on how to do that
