The bug
If you die after you lost a home respawn anchor, blocks behave extremely weird.
So if you place a block, destroy it, place a different block in the same place, the new block is replaced with the old block.
Steps to reproduce
Place a respawn anchor
Power it up with glowstone
Set your spawn with it
Destroy it
Die
Respawn
Place a block
Destroy it
Place another block at the same location
→ ❌ The old block reappears again
