The NPCDropGun plugin throws an error in the console:

Error while compiling: NPCDropGun.cs(168,138): error CS1061: Type `PlayerEyes' does not contain a definition for `headRotation' and no extension method `headRotation' of type `PlayerEyes' could be found. Are you missing an assembly reference?

im getting the samer error here, its stoping the plugin from working at all.

Thanks for your reports, working on update now.
