When updating damage values on the server/client, they will incorrectly display on clients that don't match the servers custom damage values.

Example;
Server has a custom archaic damage of x5, item has 6 base damage equaling to 30.
Client A doesn't have their config set to x5 archaic and will see the item as having 24 damage, Client B does and sees the damage as 30.

Thanks - I need to look into synchronizing config files on server. Will do so in a second.
