When you have traded away or received a Pacapillar from another user, you must update the masterlist entry. To find your Pacapillar, put the registry number into the search bar. If you do not know your design's registry number or you have lost it and cannot find the design's masterlist entry, you can ask a mod to help you!
To request help in finding your registry number, comment here: Lost registry number
How to update ownership:
Find the ownership log comment (it will be featured).
Reply to it with who you received the Pacapillar from or who you've traded it to (putting @ before the username).
Please include if the design was purchased
