(Bug) Enemies can attack invulnerable blocks

[Aeronor]

Enemies can attack blocks that are otherwise inaccessible to the player, sometimes causing damage to your base in irreparable ways.

Below is an example of the behavior I'm describing. These yetis are destroying a block directly under a tree (which of course is normally invulnerable to the player):

On the surface, that might not seem like a big deal. In fact, it could prevent the player from exploiting that block immunity for defense purposes. However, it becomes a problem in cases like this example:

I have no way of repairing that block underneath the shop. The result is that enemies fall into it and begin digging towards my base, and there is no way for me to ever replace that block. It is gone forever.

I believe that the first set of blocks beneath a shop should be changed in one of two ways:

1. Make them immune to all damage, whether from player or enemy.

2. Let them be manipulated at will. If that's not an option, at least let us fill in gaps created by enemies (and possibly replace blocks with other blocks for aesthetic reasons).

The Monster AI atack Blocks placed by Player, you can use this to let the Mobs attack useles Blocks on the way to your base.

May you can destroy the bonebrige with Spells, Explosion. then replace the, try sand and let it fall then replace.

I just tried all of those to test, the bone bridge seems immune to everything. I do know that the AI attacks player blocks, but this particular block spawned with the world, and I can't seem to access it at all.

Can you remove it now?

That did solve my problem, thank you! I feel like this should be the default behavior (I'm really trying to play through vanilla).

After your "FIX" you can disable the mod. And the blocks are invulnerable as usual.
