Last night for about 3 waves in a row I could not resupply ammo. I was given the prompt asking if I wanted ammo and to press e; however, throughout the entire wave for 3 waves in a row nothing would happen and I never got the ammo or the message that I received ammo. At the same time I was able to give ammo.
After the 4th wave, out of frustration I started tapping e rapidly and I finally got some ammo.
