Fixed a bug with the new powerup drops to where sometimes the power up would never go away even after the 30 seconds was up.
Changed up mutant spawning logic to try and make the specials a little less annoying. Now on round 1 only regulars will spawn. and then each round after will start adding a random amount of specials. IE on round 2 there is a chance for 1 to 2 tanks to spawn and so on.
I also made it to where less electric mutants can spawn. I like the idea of an enemy that can slow you down if to close but having 10 of them at one time was a bit to annoying, Now only a max of 3 can spawn in a round.
