I think I may have mentioned this somewhere before, but yeah, when you're "downloading the rest of the game" (which imo is cruel to people who think they've actually finished the download), you can disconnect for being idle. This is really, really dumb. Please fix it D:
Oh, and also, I'm asking this because this patch broke my download (again! But not on steam! Fix your updater!), and now I'm trying to reinstall. Which itself is not working.
Yes, the file management for the game is horrid.
Word of advice: Do NOT verify game files with steam's game file verify. The Spiral Knights game files that steam has are OUT OF DATE. Steam downloads outdated files, then when you relaunch Spiral Knights, its updater has to download the latest files again.
