Yes, it’s the same, separate category called “pantsdefault” as in Season #2. The difference is that while in Season #2 there are variations included in the “Pants” category in each expansion pack, there is only one default item there for any given pack in Season #1, so this is why it seems invisible there, although it’s the same. Although this is not the reason why it isn’t being exported to PSDs. 🙂
