Could be the weight of the head plus gravity plus time? How warm/humid is the place you put her?
I did consider the head, which is why I took it off just to be safe. I don’t know how much gravity and time played in it, because fondant goes like a rock once it’s dried out (as the rest of the torso seems to be). She’d spent well over 24 hours completely fine and then it just kind of decided “fuck it let’s break” a few hours ago.
My house is anywhere between 19 and 30 degrees (C) depending on if the heating on (yeah, i know - that’s ridiculous.), and our washhouse/coal shed (where the fridge - and now the figure) aren’t insulated and are fairly drafty - it’s still the exposed brick and is near the back door.
Google says the humidity in my town is currently 93% but I don’t have a clue how to measure how the humidity indoors will vary from that.
