Not to mention this will have to be re-qualification for currency, since no Baltia crew has flown in 90 days. Nor will they in the next 90 days. Must be nice to be on a 90-day tether to the sim, huh? Rinse and Repeat.
Anyway, Recurrent training can be anything. It's a simulator. You can program it to fly through a storm. You can program it to fly with one engine. You can do anything. My most logical sense is that they programmed it to do proving flights....and they JUST had it done in July, and called them to do it again ASAP and as soon as Mini-evac was done.
