Picture should show what I'm talking about: Higher level Cerebellas being placed before the lower level ones. The same goes for all other difficulties in the daily event. Question mark's there because I haven't played a Cerebella's daily event in a while, so I'm not sure if this is intentional.
Alas, my free cosmic awarded me with a Purrminator Robo-Fortune. Two lucky pulls from spending my Theonite got me a Galactic Glamour and Star Child however, so all in all I’d say it was fruitful (not for my Theo bank of course).
