[PNRP] Gamemode Development

So bassicly iam trying to make a blocking system and every system i use for blocking with melee doesnt give lua errors but doesnt work when i use it in sandbox it works,
Is there something that might interfere with damage or something like that?

Would have to go through our files to be sure, but I dont think there is anything that would stop it from working. Do you have your code available anywhere?
