If you break a block below of bells/lantens it will drop (but in bedrock edition it can flow)
PS. bells have a texture bug when it flow or bottom of the blocks. (and place on side block too)
Update!!! : When you place a bells on side block(s) it only facing one direction only (I forgot what direction)
Update #2 : Lantens dont have glowing animation inside lntens.
Please stop updating the ticket by adding new issues. The current report is about lanterns and bells not dropping despite the absence of a supporting block. If you are having a different issue with the lanterns and bells please create a separate ticket. But remember to search before creating a new ticket.
