We have been listening to all the great feedback from the community and the top thing people wanted was a guaranteed solvable mode. So it's here, you can now choose guaranteed solvable as one of the generation settings.
There is also a new mine density setting called insane. In this mode there are as many mines as its possible to cram into a globe while still making it guaranteed solvable. Be warned though this mode is extremely hard.
There is also a lot of quality of life changes which you can find listed below in the patch notes.
Be sure to give us your feedback.
If you think you have found a globe that is not guaranteed solvable be sure to post the seed in the discussions along with a screenshot so I can double check it. You can find the seed in the options menu.
