a custom exit that actives when the level is entered in the hub word can bypass this map slot problemat this point in time, figuring out how to clone the old shields would be reserved for the next major update.
Campaigns that cover each era would also require figuring out if there are even enough map slots left to do that. You'd be surprised at how many slots were used in this mod.
