Very Weird Thing Happening with 15th Pub Arma 3 Server

[Cpl J. Gregory]

So I've tried to get KAT Medical for Arma 3 server (the pub one) as before hand it was saying it was missing. I was like okay, so I downloaded it. Now it's saying Failed to verify PBO. I'm not sure what else to do. I tried repairing, disabling it and putting on ACE Pharmacy again, I have no idea what to do. Any help would be amazing, thank you!

I haven’t tried again yet but does anyone maybe know what would cause that to happen? I hope I don’t have to reinstall everything :’(

Found the fix! It updated back in December 17th and the server hasn't updated KAT Medical to that version, so just get the previous version off of GitHub and use that version instead!
