Thanks Dave. Time hadn't run out, no. I gave them until zero dark thirty (ha!) for this, roughly (as you can see from the task end time in the dumps). This was at 21.24 the day before. The HQ estimate of how long it would take (given the block) might, of course, have gone beyond the alloted time (if the HQ recalculates like this - I'm not sure; clever, if it does....) hence prompting a re-plan. Maybe?
It is following the waypoints, yes. But is this a bit problematic, the way it's done? At first I thought it was ignoring them (from other instances of this) but I see now that the waypoints (which were quite detailed and frequent) sort of expire and disappear as the lead units go through them, so that from the point of view of the HQ, some way back, it looks like there aren't as many waypoints as I planned, hence allowing it to carry out this massive re-plan and at the same time stick to the waypoints it can still recognise. Inbetween the point where it is now (at 9.24) and the next waypoint there were originally about four more waypoints, but they've been removed as the lead elements went through them. If this didn't happen (if the waypoints were only removed when the HQ went through them) then it wouldn't have been able to do this re-plan at all, because the waypoints I'd put in, along the back road, were specifically meant to keep it off the main road and the hill. Just a thought. Maybe the waypoints should be valid until they are passed by the unit I actually gave the order to? Unless I've ticked 'bypass', of course. Which in this case, I haven't.
Thanks for looking at it. Look forward to your conclusions.
