1.3.3 (bugfixes)

A few  bug-fixes and cosmetic tweaks:

• Changed at which width pixel size increases, and tutorial-advancing buttons now never leave the screen
• Fixed a crash when deleting a warehouse that's being unloaded to
• Fixed a bug where trains would split eachother when intersecting at the wrong time (hopefully, let me know if this still happens!)
• Station-windows now properly update when placing or removing lumber- or mining camps and warehouses
• Choo-choo and other sounds now dependent on distance from camera

EDIT: uploaded the OSX version too!
