Since the last update, the game uses 100% of my HDD, but when I wait in the main menu for a few minutes, disk usage stabilizes, and the game works normally without lags. I haven't tried it on my SSD, so I'm not sure if the SSD experiences heavy usage too.
There is bug for achievement: The Grind (In public matches, with the Hillbilly, chainsaw a total of 100 survivors.) I'm pretty sure I only chainsawed two survivors with Hillbilly because I never play as him and this achievement pop up. And since developers are banning players for achievements they did not receive properly…
