Unable to kill zombies that are generated with this plugin

Hi, I was wondering if I could get some help, it appears the zombies that are created by this plugin are unkillable  not quite sure when this started as I have been using this plugin for a while on and off, any assistance would be appreciated.

Doing a checkup ill get back to you soon on the issue
 

i tested it and dont see an issue regarding that.
I could think of a pve plugin that might counter damage if not included (never set servers cfg pve to true btw)

Ok no worries, thanks for looking into it. I use True PvE on the server and yes that PvE switch by FacePunch is a horrible thing and should be destroyed with fire
