There’s been an issue where late-game when the world regenerates, people can and will just get to the Lihzahrd Temple and break in, then take the altar with them and leave. This causes issues for people later on who wishes to refight the Golem and had to go through the effort of killing Plantera, just to find that some random person decided to steal the altar needed and had left with it inside their inventory.
Prevent Lihzahrd Altar and surrounding blocks from being broken while Plantera is alive
Funny extension: just make it completely unbreakable
There should be a message appearing: “You do not have permission to break the altar”.
