This is regular 'don't starve' on iOS.
Update: worse than I thought. Can't open any saved game when I close the app or turn off the iPad, even one created after the update.
I had a game saved before the July update and have never had an error message prior to now. Since the update, I get the attached error message every time I try to start my saved game.
I changed two settings between finishing the update and trying my saved game - battery saver switched to on in the app and enabled virtual stick. Based on the error, it doesn't look like the problem, but worth mentioning.
Love the game. Hope this gets fixed.
Steps to Reproduce
Start game, gather things and make a regular backpack, save and close game, restart game, instant error message. Problem started immediately after July 2017 update.
