iPhone OS v7.1.2, with strong WiFi signal only, I picked the next new level on my track (428), picked a companion, and started the level. After playing a while I couldn't swap any cropsies, I couldn't click the "i" by the companion, or select any tools at the bottom, or use the menu. I slid up my iPhone utility panel over the game and then back down, I slid down my iOS info frame and back up. It still didn't respond. I started Facebook Messenger and it worked fine. I didn't have any other app running at the time. Later, after charging my phone to 100%, I played 429 and it did the same thing but right at the first move. When I changed to the Settings..About to see the iOS version and went back tot the game, it restarted with the orange King splash screen. This is especially frustrating because I keep losing the Bonnie Booster Trail!
