Blacksmith skill not working

Since around version 1.7.8, the Blacksmith skill no longer works. If an item is damaged and repaired, the red permanent damage still remains.

Note, I modified this function and it now works:

        void HandleMaxRepair(BasePlayer player, Item item)

        {

            if (player == null || item == null) return;

            if (config.tools_black_white_list_settings.max_repair_blacklist.Contains(item.info.shortname)) return;

            if (Interface.CallHook("STOnItemRepairWithMaxRepair", player, item) != null) return;

            if (!item.hasCondition) return;

            item.maxCondition = item.info.condition.max;

            item.condition = item.maxCondition;

            item.MarkDirty();

        }
