I screwed up big time last night.
This time, I'm going the full agricultural route. I have a full farm of pigs, cows, wheat, chickens. I also have a laboratory downstairs that I'm messing w/ redstone and switches, lava, all that. So I had a bucket of lava on me while i was in the chicken coop, marveling at how many chickens I now have. Theyre the only source of feathers for arrows, so Ive been really concentrating on the raising of chickens and had quite a lot. Key word here is "had"..
So, wheat in one quickslot (for feeding the chickens, makes them multiply) and lava in the other. One wrong push of the hotkey, one wrong roll of the mousewheel, one wrong click of the mouse, I dont know what it was since it was all a blur once the chaos began. Before I knew it, there was a pool of rapidly expanding lava in the center of my coop, and flaming chickens in the air all around me. As if that wasnt bad enough, the fence caught fire and since all my fences are close and interconnected they ALL caught fire, releasing flaming chickens, cows, pigs, everything. On one hand, it was a total nightmare knowing all the effort that I'd went thru to create the farmstead. On the other, I have to admit that it was kinda funny. If I'd only been recording!
So it wiped out pretty much my entire chicken population in one fell swoop, along w/ most of the feathers/chicken that they drop, leaving me with one lone beleagured chicken. Thankfully the idiot cows and pigs were for once smart enough to stay away from the lava and fire, and I just had to round them all back up.
