I'm working on a daily puzzle game, like Wordle. Last night I published a new version but when my wife tried it on her iPad it was completely messed up. It was displaying the wrong buttons, sprites were in the wrong place, etc. I cleared the browser history and then everything was fine, but what caused the problem in the first place?
When the game is running I frequently save it. If players start the game, and the date matches the save, then I load the saved game. Could this cause an issue if the game was updating to a new version at the same time? Also, she had left the game running overnight -- not sure if that could be causing problems...
What else could have caused this issue? Any ideas?
