You can only hold a maximum of 5 lives. So if you win 5 lives during your rank up, but you already had 5 lives, you get no lives because it only fits 5 :(
Hi, I don't know what other way to explain it :) The new rank up on Candy Crush. When I ranked up to level 15, one of the things it said it was giving me was a new friend. I thought that was odd, but I didn't see any new friends so I'm not sure what the developers meant by that award.
Last time this happened to me it was because the upgrade now exceeded the capacity of my device (ie my iPad/iPhone was too old to handle the upgrade) :(
If you make one stripe, it's direction is determined by how you made the stripe. If you made an up or down movement in making the stripe, that stripe is up/down. If you make a horizontal movement when making the stripe, it forms as a horizontal stripe. That is what I have experienced.
I've found that those challenges only count stripes you specifically made, or that naturally occur due to movement on the board. It doesn't count stripes made by touching a speckle against a stripe, or stripes that use up your remaining moves if you finish the game with remaining moves.
