Mod is crashing my server due to what I believe is a conflict with the TF2 mod and the SRP Parasites mod. Whenever a TF2 mob interacts with a SRP mob, the TF2 mob becomes corrupted and the server crashes.
I'm currently searching for a fix that doesn't involve removing either mod.
java.lang.ClassCastException: rafradek.TF2weapons.entity.mercenary.EntityHeavy cannot be cast to net.minecraft.entity.player.EntityPlayer
java.lang.ClassCastException: rafradek.TF2weapons.entity.building.EntitySentry cannot be cast to net.minecraft.entity.player.EntityPlayer
java.lang.ClassCastException: rafradek.TF2weapons.entity.mercenary.EntityEngineer cannot be cast to net.minecraft.entity.player.EntityPlayer

(EDIT): The mod "Parasites Addon : Overlast" was creating errors when npcs attach SRP parasite mobs, I removed the Overlast mod and everything is working smoothly.
