is there any way to add the gravity spikes (DG-4) to the box? I've tried the hero_gravityspikes_melee and it won't work

ever since the update for the scripts for the weapons (PPSH, etc.) I instantly get GAME OVER when I spawn into the map, I literally didn't even touch the scripts folder after replacing it with the new one, but if I don't replace it, I get the client mismatch error, please any help???
