After unlocking second city can't collect first citie's ships, what is the point to have this achievement if it's impossible to achieve it ? Missions times way too long. In first city I got same 4 ships. Too many ads and then asking to buy gems to open loot boxes...usually these kind of games do have one or another this has both...dissapointent, because just after couple hours game killed itself with bad in-game reward/achievment system. Can't believe it has good review rating, makes no sense.
