Got an extremely good character going; a hitchhiker with Robust Genetics who is currently wielding a nodachi and stomping everything in his path. Made it to winter, started decorating the emergency shelter (started off in a good location next to a mall, which I eventually cleared out).
Then one day… I accidentally stood ON the stone fireplace I had built earlier in the year instead of NEXT TO it. Lit a fire, cooked some food, and then – wait, WHY IS MY HOUSE BURNING DOWN!!!
I barely managed to get out before the whole thing went up in a blaze. Luckily I had read pretty much all of the skill books, so even though they got toasted, I didn’t lose much. Most of the really important stuff was stashed in the basement; I just relocated everything to a nearby LMOE shelter and I’m now constructing an aboveground fort + palisade wall.
Something I learned from all of this: apparently anvils are flammable.
