Your edits stay, and stop means stop

Two bugs this week, both about trust.

The first: if you changed your audience by hand and then kept chatting with the study designer, a later update from the chat could quietly undo your edit. Numbers in the audience picker could also jump while you were typing. Both are fixed. Your edits are saved as you make them, the chat no longer overwrites them, and if a save ever fails, we tell you so you can retry instead of finding out at launch.

Seeing progress, and stopping it

The second: while the designer was working, it wasn't always clear what it was doing, and the stop button sometimes couldn't be clicked until it had finished. Now there's a single status line that updates as the work moves along, and stop works at any point. We also fixed a case where you could end up with an empty reply. If you've changed your mind halfway through, you shouldn't have to wait to say so.
