There are several bugs and problems I am having. One being that when shooting the AR at those gas spawning clouds, the darts stay in place and don't despawn, basically leading to the next infected that walks out to pop instantly.
Another is the health pill thingies occasionally give you overheal (meaning your health raises over 100) and leads to your breasts and belly to no longer be visible until damaged again. I experienced this when using the achievement perk thing that makes the pills heal extra
Round 10 on hard is extremely laggy, when spawning the horde to the point my game nearly crashed.
On the map "the bank" near that alley with the easter egg you added, when inflating a blimp, it can be knocked out of reachable distance essentially bringing the game to an endless mode where you cannot progress the rounds.
Items tend to disappear when 2 infecteds are popped close to each other.
Finally, I would really appreciate the sawed off to be upgradable because it would make the thumper actually viable since you can't use it effectively from waves 1-5 because of self damage and god forbid an infected gets too close, you're helpless.
I would really like to see some of this adjusted in the next update, thank you!
