persistent problem where level for unlock is reached but unlock does not activate.. newspapers/everything at 3900, movies at 5250. also, unlock screen shows everything x 2 at 3900.. but has 4 total duplicate icons.
to get rid of a strong creature, capture something weaker during the next mission. only the strongest captured for a given mission follows you to the next, and if you capture nothing, I think you simply retain whichever creature you began with.
totally geeked out on this and set up a spreadsheet to calculate cost effectiveness of the different investments in order to guide progression. thanks devs!
