I just worked for four hours on a Bitsy game. It has a lot of rooms and exits. Out of nowhere, some tools stopped working, so I saved/downloaded the game and reloaded the browser page. I've had to do this a few times when things get glitchy.
Only this time my game came back corrupted. My avatar had reverted back to the default, the default room had appeared, and all the names of my rooms were blank. There was also a room that had all of its exits deleted.
I tried loading the file I had just saved (which I replaced my earlier file with -- doh!), and it was the same situation. I tried to salvage it, but the file is pretty corrupted. The room name data is damaged and it's making it impossible to create new exits.
TLDR: How common is it for Bitsy game data to be corrupted? Is this because of the number of rooms I had? And are there ANY solutions? Do I really have to start an entirely new file and throw hours and hours of work out the door?
