Just downloaded the new IOS version 3.0 update and I've found one bug that crashes the game out to the home screen so far. I've noticed the crash will occur when interacting with Jack's health bar to check his stats immediately after interacting with a forge. I have been able to consistently reproduce this. The crash has also resulted in the loss of ingots that were in the forges in question when the game crashed (thankfully they were just copper and iron ingots, but still not fun).
My device is an iPad Air 2 running iOS 10.1.
Hope this gets fixed soon. Other than that, keep up the good work Pixbits!

Update: this crash is also happening with wooden chests. I'm guessing there will probably be other items as well that trigger it.
Update 2: This same crash is also causing Jack to literally lose the shirt of his back. When reloading the game after this crash Jack loses the Pixbits shirt IAP if he was wearing it. This is also happening with the Pug pet IAP if it was equipped. Not fun.
