Polymino + glass cards issue

[Elemental239]

Description: I used a polymino onto 4 cards, one of them was glass. After several hands glass card breaks.
Expected result: it seems to me that group of 3 cards is proper way to go. If not, just disband the group
Actual result: group is not marked in deck view, but it is still exist, you may draw it or get in arcana pack screen, but it is completely invisible, so you cannot play or enchant it or make smth
