I have 4 boards. My main board has copies of cards that exist in the other 3 boards.
I have implemented Butler automation to automatically add card attachments upon copying a card, both in the initial and the newly created cards. This has been working fine and this is not the issue, I am just posting all the info.
Suddenly (I believe this happened when my Gold Membership expired), the cards in my main board which had perfectly working attachments (of their "mother cards" from which they have been copied) have stop showing up. This happens only to cards that have card attachments of a specific board. Card attachments to my other 2 boards are showing up just fine.
