With free you mean that the bar doesn’t reset again?

I did these levels being lvl 36 and my bests birds had level 6 of mastery, so don’t worry about that. If you have surveillance problems I recommend samurai, rainbird and druid. Is a very defensive trio, you will do It so slowly, but at least you will move along.
Another strategy is build a trio that can delete easily the samurais using marksmen, druid and canoneer/samurai.

I have the same bug and I use android. In the box I could see a pig and read something about stamina
