I agree, sounds like a bug. I see your point, Q, but that 'freshness' is already a factor in the form of supplies spent and damage received in the previous battle(s).

Shields would likely be fully recharged within a few hours, Shield Recharger or not. There is, symbolically, supposed to be probably at least a few days between each hex traveled( and thus between each combat ), like Munch says.
