sealed the modify lane because the popup fixes have broken the maze, i know how to fix the maze but will tend to it later as it will be time consuming and tedious work.

added a checkpoint near start, and boost activation zones on all shortcut portals, also added a sign wich indicates if both players are present in AND to the next stage

turned the quantity maze into a seperate project since it was already bigger than the contraption map, you can still also visit it on the contraption map though.
