Well I was blowing my shit up, and I went to my iron farm. This cell of villagers always looked weird. They appeared to be stacked on each other. So, one tnt in the cell... BOOM. And this happened. I had the glitchiest villager cell ever. So glitchy, that while they were in this pen, with no doors around, they continued to reproduce. There is like 40 of them.
Here on villager news there is an outbreak at watkinni1's iron farm. About 100 villagers have spawned and are still spawning...
Great, now Wat has to deal with an overpopulation problem. Honestly, those villagers need better protection... some iron armor will do just fine.
