I just made it to 8009 on Windows 10, and as soon as the level starts, it says "Oops" and then this error message (and I lose a life). Happens every time I try to play the level. :(
One example of a level that was changed to an exact repeat of another level is 3842. It's an exact repeat of 3629. Both levels show up like this for me on Windows 10 PC and Iphone. The same day that I discovered that, another player checked on their phone, and 3842 looks like this, which matches up to videos I found…
