I loaded the map, and was going to explore the map a little, then come back to his hidey hole, but a major bug has occurred: a swatch of land has gone missing! Luckily, it missed my workbench, but it destroyed a dig site, 6 ladders, and a good deal of wood.
If you think I just destroyed it to screw with you, note that all the snow is clearly only just starting to come back. Now tell me how I could have done that all at once.
(If this was the save break and that's all that happened, that's actually pretty lucky.)
