I was thinking of adding them in at some point.
Large scale process in mind:
- Look for any 5x5 area underground with no cave or man made walls, flooring doesn't matter? oh V1/V2 it did, ok maybe
- Add "unstable ceiling" items to the area, it is an animated dust cloud with some small falling rock, gives any players around a warning to run, Run, RUN!
- Wait a 30-60 second cycle and then each item has 50% chance to cave that spot in or just remove the item
- Spread some rock debris and dust clouds in the area, dust clouds cause stand damage 2-4?
- caved in spots can still be mined again for the same ore? not sure, in V1/V2 it allowed it a few times
- land above would not deform
- any player getting a direct hit... dies
Small scale:
- find random single spots and do the process above, like 1-10 per v-day
