I've noticed that sometimes when I play Awesomenauts, I'll teleport back to the shop to buy items, and everything I've purchased up to that point has to be purchased again.
I'm assuming this is a bug, but I'm really hoping it's intended behavior. As in, I bought Damage +2, played a bit, teleported back, and had to buy Damage +2 again, giving me a total of +4 Damage. However, I worry that this is not the case.
Why does it make me repurchase items?
