1V91 - Seems less stable than 1v90+ interim versions

Just that a program I have been running for awhile (days) off and on to toggle a puck from another puck and gather statistics, now just dies on both ends after a few hours. Before I was getting a timout 7 error or something like that on the transmitter after many hours. But a button press would reset the timer in code so it would start up again. On the receiver the connections would continue to succeed but the action, the toggle, would stop. But with 1v91 it all worked well enough at first but then just died and non-responsive. Just sharing experience. Nothing concrete. I think I was on the 1v90.12 on both ends before.
