EXPERIMENTAL: Ditch iwd verefication
Browse files Browse the repository at this point in the history 
I don't know, this apparantly only causes more cons than pros, looks like there is some possibility to abuse it and make the server lag. Tried to modify referenced iwd's with this and still was unable to join so idk. Also fixed grenade and vid restart callbacks. Also added possiblity to force client download.
