Cloud Data Saving
Stormworks does not currently have cloud saving. This means data between computers does not save at all. Every customizable feature of Stormworks is not saved. This means that All Settings, Vehicle Saves, Character Customization, and Game Saves will not be saved. This makes being able to work on builds from PC to PC almost impossible without downloading the XML file and manually uploading it to the other PC, which becomes a just so you can build on Stormworks.
I hope this feature is added, it will be a major quality-of-life improvement, and solve one of the biggest problems I've been having with the game.
