Bug Fixes - v0.6.0.63

Just a quick update as was made aware of a crash issue today. Was a problem with contracts and when they lapsed could cause a crash. That's now fixed, along with a collision boundary issue when placing a default station in scenarios (was out by a tile). So now consistent with placing a custom station (along with the dashed outline).

Patch notes:-

• Improve: Show dashed line outline on default station placement.
  
• Fix: Station placement, fix collision check with default station.
  
• Fix: CheckContracts, if lapsed skip complete check, as deleted (crash).
