Active is one air group consisting of one unit comprising one tanker. In about 10 seconds (game time 120731) a refuelling event starts.
The group now continuously goes through refuelling cycles.
While this is not new now that refuelling operations continue until fuel is expired it becomes tedious. Also if the fuel to offload is small the "Refuelling is finished do you wish to split off tanker" request comes up at the end of each cycle.
Reproducible, any situation with a tanker having no aircraft to refuel and group range relative to home base low.
