It would be nice if dropped items didn't disappear after, what is it, 30s. Sure we get 3000 each round so "hey, you can just buy them", but scavenging items was one of the many nice things about the game.

I lost 100 coins too when I bought a duck skin. Turned out someone had hacked them, duck skin was fake and coins got me nothing. Didn't realize I could ask for them back.

The amount of points required to get a coin is too much (imho) when you look at how many coins you need to buy skins, and the skins which are available.  Maybe getting the human skin & the zombie skin for one single price rather than having to buy both.
