RunFights progress bar sometimes hangs even though progress actually completes

[GaryA]

For very small events where there are only 2 groups, teams of 3 or 4 should cause an error message.

Test case is an event with the following entries:
Team 1:
Robot 1a, Robot 1b, Robot 1c
Team 2:
Robot 2a, Robot 2b
Team 3:
Robot 3a, Robot 3b
Team 4:
Robot 4a

RunFights appears to hang/crash at 75%, but the draw does appear to have been done properly. If the fights are shown the draw looks good with 4 groups of 2. All the fights can be run right up to the final. A 2-robot group works properly.
There is just something that doesn't allow the fights setup to believe it has completed.

At least sometimes DoDraw and RunFights do complete properly with only 8 robots across 4 groups. Maybe the issue is more to do with mySQL pausing?

DoDraw completes OK, but sometimes RunFights appears to hang/freeze at less than 100%.
The fight setup does actually complete. The progress file in antlog/runtime shows 255/255 done but the file has not been deleted. The javascript that monitors the progress seems to lose track of the progress file (???)
