I think. It's bizzare. Me and my brother have a LAN world which is survival based. We live in a NPC village which we expanded later on. The Villager population decresed to 1 villager total, and he had a really good trade (something like 1 fish for a fortune 1 and unbreaking 2 diamond pick or something idk) but we wanted to save him so we put him in a small auto-generated hut and blocked the entrance so he couldn't get out. This was about 2 months ago, we honestly forgot he was there lol. I logged on today and heard some explosions and while I was walking around i saw his hut was destroyed and there was a crater where it stood. The area was well lit so I don't think it was a creeper. There was a second crater not far from his hut that was also new at the time of this discovery. No idea if it's related. My only theory is one of our Iron Golems threw a creeper into the hut on accident but like I said, the village is fairly well lit so I have no clue what the heck happened. This seems to have happened on previous worlds too.
This is modded minecraft, but I haven't gotten new mods as of recent. I would post something about my mods but I don't know how to fit it here.
(Don't tell me to use pastebin. I don't know how to use it and quite frankly I'm probably not going to learn it)
For some reason it stopped letting me edit so let me just rephrase that statement:
After some exploring, it seems like the village is just exploding for lack of better words. Even a mine we started (and neither of us has been down there in over a week) had been exploded. As far as I know, there are no mods installed that have meteorites or anything like that.
Farms, Buildings, Mines, and at this point, random plots of land are just blowing up for (to me) no reason.
