Aloha,
I am getting a crashes while working in the c3 editor once every few hours. No error reports, just "awe snap, something went wrong : reload page?". I have also had a few hangups while in the sprite editor, where when I click to close, the loading the wheel pops up and just keeps on spinning and the project is frozen. Obviously all progress is lost since the last save.
I know these details won't be helpful for diagnosing the problem, but I was wondering if others have other similar issues. I have only had a few crashes while working in the editor on the browser, and all of those were reproducible, provided error reports, etc... but as a standalone app, the crashes have been getting on my nerves. So far, I have been able to reproduce nothing. The projects aren't complicated either, just basic templates projects that have minimal stuff in them.
I'm going to keep to the app to see if I can't spot the reason for the failures and just exercise using the save button more frequently.
