Thanks so much for helping. 
I'm not a math person, to be honest. Or even just a numbers person. Coordindates, I can do, that is about the extent of it. Gotta admit that I don't understand the formula. Which is normal for me. I don't understand most any formula. I'd at least like to take a glance at each regenerated area and see if I can deal with it, or have to do something. One of these was in town-center but I lucked out and it was just a simple barn that I just rebuilt in 15 minutes. Good as new. No underground tunnels that were disconnected, either. The list of regenerated chunks is actually quite long, but it seems to be only little pieces here and there, all from the same big, biiiig file. r.0.0 ....
Maybe the SD card is slowly dying, I'm not sure what caused the bad chunks. Instead of 20, there must have been hundreds sheep in that pen. 5 of the 15 minutes I spent on "removing" sheep. Ended up with 10 or so stacks of mutton.
