PC - Steam, using xbox controller. As survivor (have not noticed on killer, don't play killer that much), when running, many times I stutter or just start walking/going slower instead of sprinting. Isn't linked to map, survivor, controller hardware. I'm not sure what causes the bug, but it does trigger at random points…
Cosmetic contest was closed before May 23, even on the East coast. According to the official rules: "The Contest begins and ends on the date and time detailed on the Contest Page, Eastern Time ("ET")". I LIVE on the east coast and tried to submit before midnight and was unable to because it said the 'campaign ended'.
