Wondering how the cave ins work at the moment, how they deal damage and etc. Want to get into mining and I would appreciate it if someone could explain that stuff for me.
You're always expected to be knocked out (= taking out full SHP you have), the 12 additional HHP damage you took could be from additional concussion by faceplanting on knockout...
Yeah, I lost about 50 HHP as well a few days ago when I was trying out mining. Gladly I got lucky and smelted a bar of tin with only 3 ore and now I'm mining chalcopyrite.
