I then can no longer access "sm_grenade" and the grenades I pickup and throw have no Prototype Grenades function so my only conclusion is you have something setup wrong. Everything I have tried (and I've tested multiple times for you) works as expected to prevent me from having Prototype Grenades types when I shouldn't.
Are you using the latest version? This blocked the types when equipping the grenade.
I sent you a proof video privately bro. I believe you will understand if you watch.
