I forgot to mention that we had it on "easy" survival. Originally, there were huge numbers of mobs - both peaceful (horses, cattle, etc) and hostiles. Then it just stopped. We tried putting it on "normal" survival and it didn't help. We thought our farms might be saturating the mob count so we killed animals - didn't work. We wandered several hundred blocks from our bases and still no mobs. On occasion, we will get a few for a while (including hostiles) but most of the time nothing. My son built a mob generator (using a dark space and water) and it will rarely get anything. We have both played for years so we know something is abnormal. Isn't our first rodeo.
