New shop lags the game.

[TrollMacLeod]

Each time I open the shop, it freezes the game for 1-2 seconds. This happens when I'm in the home base, or anywhere else on the map. My settings have been unchanged since I first installed the game, at which point it ran just fine, but now the new shop makes the entire game pause.
