After a building is created, we get this option:
"Refund Within 24 hours after you built a building, you can here refund the building (if you chose a wrong position, the routes are bad etc.). When you refund this building, you will receive your 100000 credits back"
However it does not make it clear that all employees and vehicles are DELETED COMPLETELY when this refund feature is used.
This has lead to a lot of time spent earning credits and building up the station has gone to complete waste and I won't be bothering with this game any longer.
EDIT: Why on earth can't the move option also be free for 24 hours? It suggests you might want to move it the delete window. Developers need to check their interface usability skills.
