WIJ Weapons glitch? [Glitch]

Ive recently met a few WIJians who, have claimed that the weapons have glitched and wont kill the raider, I never did believe these few, until, today I went to Cobalt, and bought an SUF a raider was in the base and, I shot him multiple times with the SUF,  but we would not die, his health would come back right after I shot him, has anyone else been experiencing the glitch? It may have been caused by roblox's new updates.
