Office elevator logic was written as
can reach Underground Tunnels OR can reach Office AND have Key for Office Elevator
Meaning that key for office elevator was not required if Underground Tunnels could be reached when it should be.
Changed to
(can reach Underground Tunnels OR can reach Office) AND have Key for Office Elevator
Fixes rule logic for location 'puzzle solved three floor elevator'. Missing a parenthesis caused only the key requirement to be checked for the blue maze region.
