While playing in windowed mode (only way I play) I have seen that the Design Unit screen seems to increment constantly the usage of memory of my computer.
Whenever I click that menu option from another menu, the memory usage of the game increases. If that was not enough, whenever and each time I try to equip a traveling cloak, the memory usage increases again. Oh, and shields currently seem to be impossible to equip. No matter how much I try, the shield doesn't get equipped. And memory usage increases each time I try.
