»IIRC, she doesn't take away/store your 45 piece (Storage Slip 14 does that) when you trade it on its own. The new and old sets use different coins, so there's no space for any error to be made.
If she did take your Idi's Gloves, try trading your Skadi + 15 gold.
This. She won't take the 45's at all unless you trade all the items together.
Also worth noting you CAN mule plans to characters on the same account so don't trade those to her unless you're sure you want that character to use them. She won't return them.
