Some Minor Fixes and Updates — Dooblets Steam update #733523

- Updated the Start Zones to only activate when 2 or more players are present. - Fixed Softlock that caused infinite loading screens when the host would exit the game with more than 2 players, while loaded into a level. - Changed how Sacred Blocks work to prevent Ghosts from getting stuck. - Made a tweak to Up and Down with the rotation of floating objects. Thank you, Rombo :)
