As soon as 36965 was active again, it replaced 22021.

Why a section of the route was served by neither vehicle, I do not know.

Probably covering mileage then and once 36965 was fixed that will have gone to where it should be to pick it up again. Obviously by the time 22021 gets to pick up the service there'll be a gap unless it ran very late, pointless on a frequent service though.
