LOVE the game. Since this update though, a couple of minor annoyances.

1. Towers don't always indicate when abilities are available for upgrade.
2. If towers do indicate when abilities are available, the upgrade arrows don't always disappear once ability is chosen, but the animation of these arrows stops.
3. Ads don't always play. Loot Bonus (just does nothing), Decrypting (reports Something went wrong) or Watch Ads (play button is missing). Clearing cache never used to work for this, but force stop did. Now it seems I sometimes have to do both.
   None of these issues appear to be reproducible (of course, that would be too easy!) but I ran thru a game with debugging on, and it showed 1. and 2.; the ads worked fine.
