Mid-Match hang due to smart dashboard?
In a few matches in our week one district, we observed a few seemingly random losses of control on the field, mid-match. The FTA attributed this to an issue with smart dashboard (which we were using), and informed me that similar issues were seen by a team in California in week 1, and that a fix should be expected in the coming weeks.

We disabled smart dashboard, and removed several unused sensors from code; and didn't see the issue again in our remaining ~9 matches.

In the match where it was decided that the issue must lie with Smart-Dashboard, the DS log was free of errors until robot control was lost (at which point motor watchdogs began barking), and we saw behavior that I would attribute to the main thread being stuck or crashed. No losses of communication/robot code were observed during the match.

I'm curious if this issue has been observed elsewhere, and if there are any fixes planned to resolve it. I believe this issue is separate from the one identified in the other "Serious Bug" thread because it is not occurring when a connection is severed.
