I just noticed this. I'm on the new challenge path, but breakfast used that skill and got me a bunch of items. When I look at the item description, it says "this item is too old to be used on your current path". However, when I look at the list of restricted items, there is no haggis, no Microplushies, and so on.My guess is that you are reporting this here because KoL mistakenly allows Summon Geeky Gifts to be cast, and then you can't use any of the items after that.
The bug is that KoL does not not list the items on standard.php. Once it fixes that bug, KoLmafia will work as expected. I agree with lost that putting in special code to work around this bug seems like wasted effort.I don't think mafia should work around that issue.
