Bug [ ]: Game Review - occasionally doesn't complete and needs to be resubmitted.

This is an intermittent bug and is hard to duplicate. Below is an animated gif showing the problem. Granted it is pretty boring, but does show no progress of the progress bar or score chart.

The Bug:
The analysis never completes.

One way I have reproduced the problem is multiple times from Analysis to load a stripped pgn file, just the moves, and run the Game Review. Occasionally the report does not complete.

This game demonstrated the issue and may reproduce the problem if run multiple times from Analysis tabs.

1. e4 e5 2. f4 exf4 3. Nf3 g5 4. d4 Bg7 5. Bc4 Nc6 6. O-O d6 7. c3 h6 8. Bb5 Bd7
9. Qd3 Nf6 10. Re1 O-O 11. e5 dxe5 12. Bxc6 Bxc6 13. Nxe5 Qd5 14. Qc2 Rae8 15.
c4 Qxd4+ 16. Kh1 Rxe5 17. Rxe5 0-1

Note: Checking the archive shows no indication of a completed analysis. So it is not that the window didn't update. The report just didn't finish.

Edit:
A red error message just flashed** at the top of the game window.  The Review tab disappeared and the Analysis tab had Game Review button.

** Bug 2: This message should stick around. It had an X box, but I didn't click it and the message just disappeared after a few seconds or due to activity in the window. Not sure which.

Seems to be quite frequent the past week or so.

I've experienced this issue intermittently for months too. I find it especially prevalent if I have multiple analysis tabs open.

Additional strangeness around failed Game Report load occurs sometimes upon visiting the report. I run at depth 26 and for a recent failed load with error message

 and the analysis report loaded with a reported depth of 13!

I appears the failed load saved a report with less than perfect info.
