0004845: Freezing oceanic water causes cave-ins and makes the game freeze too
I embarked on an 6x6 area (approximately), covering a whole island.
Winter came. The southern and western waters froze without incidents. In the month of Opal, the northeastern waters partially froze. Then, I received several cave-in messages (usually 2 or 3) from that part of the map. Each of them was separated by a time ranging from half a second to a few minutes.
After a short while, the game blocked.

The number and the time between cave-in messages varies when I try to reproduce the bug, but the game always block after a few minutes.

- Embark on a whole island where the weather is cold enough to make the ocean freeze part of the year
- Wait until winter is upon you

Assuming that the game actually unfreezes, eventually, most of the report would end up being a duplicate of 0001899. The general oddness with freezing oceans might also cover your cave-in issue.
