[ARCHIVED] Ice in fridges don't melt after leaving and re-entering the lot

That's what happened! I've been playing on an off-grid lot, and while the fridge seemed to work fine at first the first day I was playing, very quickly the ice stopped melting. I may very well have traveled - or at least gone into build mode and back, reloading the lot. Now I've played a few more real life days - no mods - and the ice in the fridge is always 100% without my Sim ever needing to add any. It's been a couple Sim weeks in game.
