i may have put like 100 margin and now i cant play the game how do i undo it

It doesnt seem time based, and it doesnt seem space based. So what makes this 4D?

Anybody have any ideas why this is happening, i don't think that the game updated and i already played for 100hours without any problems. Now it crashes on start

Started playing yesterday and I love the game, when I was close to winning the first one, came down to the last four possible blocks with 2 mines: https://i.imgur.com/VlLD4uo.png Basically there 6 possible arrangements of mines and free spaces, and 2 of those were gave the same arrangement of tip numbers (1) around, so in the end had take a chance. And Lost. My frustration is immeasurable, but i persevere....

i've exported some games, and i'm able to import them to play them again, but can't find the files in the exports folder. does anyone know where they're stored?
