I have also been lucky that non of my dolls have taken any spills.
I have purchased badly damaged dolls in the past and have resorted to buying parts to replace the damaged ones. I mostly stick to modifying the doll completely though.
I think it's kind of lucky that dolls take spills. As a buyer of second hand dolls, broken fingers, chips and cracks usually mean a good deal on a doll in the market. *naughty*
