I have the same question. I changed something, but it is not working, like I want.

// Update 27.10.2019        
//entity.health += num;				
entity.health = entity.MaxHealth();
				
entity.SendNetworkUpdate(BasePlayer.NetworkQueue.Update);

I think, that we can give the entitiy their maxhealth, but ingame in have the normal repairrate.

Maybe a guy know, what is to do and can help us.

Thank you in advance!
