0.2.3 - Minor updates

Another small update to get some fixes we made during the week out there. We have:

- Fixed a bug that allowed you to extend stations into town tiles, and sometimes crash when doing so
- Fixed some broken art tiles in Tipsy Tavern
- Fixed a crash that would happen if you deleted a station when a train was loading or unloading at that station

Savegames are broken by this update, so if you need a Steam branch to finish an old game, please let us know!
