I will change the title of this topic maybe later.
I was trying stuff with nectar bottles. They are ageing in two different nectar racks, one you can buy, and one you can sculpt. The last one is a masterpiece and I was hoping it will raise the money of nectar quicker or more. But it doesn't.
However, beside that disappointment, I saw my nectar is still aging and the value is pretty awesome ($90.000,- per bottle and raising), but the weeks it said it is in my savefile sticks with 15 weeks. Eventhough my Sims lives now for... what will it be? Several simyears or so, if you count 52 weeks in one your in game too. The fact is that the bottles are also almost that old, although the game doesn't seems to count it also.
Is this a bug, is this a Easter egg (in December) or is this something else?
BTW, just so you guys know: if you get nectar from another savefile, the nectar aging weeks start to count from 1 again.
