Infection - Fixed issue with bedrock applying damage. KitPvP/OP - Added '/stats reset deaths' for players to reset their death statistic. New Spooky Lobby - built by Rythen & Janice
Unless it was already fixed, i'm pretty sure the cooldown for the egg is still broken. ( if you die as a zombie, the cooldown will restart ). The cooldown shouldn't be based on when you spawn, but the last time you use the egg.
