Fixed! You guys are awesome!
Your progress only saves when you either quit or the game ends, unfortunately if you leave the game by any other means it wont be saved; although your inventory is updated automatically.
From the character packs of levels 4-10, in 5 of these packs you will get a character piece. The last character piece to unlock the character will be at level 10 and therefor you would have unlocked that character.
also as you state, in 5 of those packs from 4-10, we are NOT getting pieces
we need one more engineer (not the newest one) and are up to level 8 and still only have 1 piece
I think there is an issue with the system
