[MIRROR] Properly fix postpones in the mc. (#6524)

* Properly fix postpones in the mc. (#59813)

I broke shuttles and other things by trusting queued_time.

This fixes it better, by tracking the ticks it's suppose to miss.

closes: #59805 (this doesn't actually work anymore it seems)

* Properly fix postpones in the mc.
