If set to a value greater than zero, the BuildingType periodically heals all of the owner's UnitTypes on the map after eachby multiplied by this flag's value. Additionally, all of the player's UnitTypes receive a wrench pip next to their health bar which blinks every time the UnitType is healed by this logic. The effect is constant for as long as the BuildingType is intact and owned by the player.
If set to zero, it completely disables the flag (the health bar pip doesn't even appear) as opposed to simply not healing.
The effects of this flag stack for every additional building a player has with this flag set. This means that for example, even in vanilla Yuri's Revenge, it is beneficial to capture several Tech Machine Shops, as the vehicle healing effect becomes greater with each additional Machine Shop.
