What happens to data collected, but not uploaded for one reason or another?

Most common for me is the app is closed (perhaps forcefully by the OS) before I upload it.

Nothing is lost - observations and networks remain in your local database, and the next time you upload, the data composition task starts at the last-uploaded database marker, not the "run"

Great, thanks. Some of the "lost" runs had 3,000 - 4,000 new networks.
