Ryanair Divert back to Kaunas?

[old,not bold]

I notice that Ryanair, identifed on FR24 as RYR660M, has just landed at Kaunas after departing earlier and then turning back from the coast; the FR24 trace has just been wiped.

Anyone know why?

Update: Now, at 1613Z, the aircraft (presumably the same one) has just departed, identified as RYR7637.

So what happened? Almost certainly not very serious, but intriguing.

Nothing happened. It did exactly what it was supposed to do (EYKA-EYKA). No 'diversion' involved.
