Simply Paul: Revisiting the location of this at half-term may have been a mistake, as it told me a further replacement probably won't last long either. Rather than keep putting caches out here, I've decided to let this one (it was the GEOCACHE one at the Geolympix, in the little tree in the meadow) go, with half an eye on new ones for the 2018 Winter Geolympix Mega (fingers crossed). Thanks to everyone who found it and sorry to those who didn't. Physically long gone!
