I have noticed, since switching to Technic 7.1.0, that NPC villages turn into ghost towns in the matter of a couple of days. I had been looking for some trees to start an initial base, and found an NPC village. Running out of daylight and figuring that this would be a great place to crash for a few nights while I got things set up, I entered one of the villager's homes and began to set up shop. He didn't seem to mind too much. But I noticed something odd after gathering some of this fellow's wheat in the morning (I replanted it and... again, he didn't seem to mind): Most of the cows, as well as all but one sheep, were gone. I led them into his house and then noticed something else, after I had gone mining. The villagers were gone. I'm not sure if this is a bug or not, and would rather not bother the bug board with this if it is not, but I'm wondering if this is normal. I think it might be a result of the Mo Creatures mod, as I do not recall this happening to regular NPC villages in the 7.0.1 version.
