Why a ender dragon destroys the end stone bricks if they are made of end stone. And ender chests made of obsidian. As well as the chorus plants and purpur bricks.
Fix it:
1 - end bricks
2 - ender chest
3 - chorus plant
4 - chorus flower
5 - end rod
6 - dragon head
7 - purpur block
8 - purpur pillar
9 - purpur stairs
10 - purpur slab
