I tried to use fill command to remove a house I built so I could move it back. The paintings were left behind and started to create hundreds of painting items whenever it was updated. I tried to break the paintings, place blocks adjacent, save and quit then rejoin and fill the area with blocks. Only using TNT would stop it temporarily.

This is a very bad bug and makes the game unplayable due to the lag it creates and the fact that it cannot be stopped in game.

How to reproduce:

• Build a structure with paintings inside
• Use a fill command to remove the structure
• Update the painting blocks
• I did also try and use structure blocks and selected the 'remove blocks' in the options but nothing worked

Observed

• The paintings did not break and created hundreds of painting item entities a second when they were updated

Expected

• The paintings disappear along with the other blocks
•
