Below indestructible is: When biters try to path through indestructible entities they attack them, despite being able to do no damage. I believe the pathing biters are expected to treat an indestructible entity the same as an entity with its health set to 0 and know to path around it.

I can't find a definition that this ignoring indestructible entities behaviour should be expected, but this similar bug looks to support it:

Can you provide a save or scenario showing this behavior?

It works as expected when I test it

Sorry I was quickly logging this as I came across a note I made when making a mod ages ago. I had assumed it was more common than it turns out.

The attached save reproduces the issue: The issue seems to be if the biter is already attacking the entity and then the entity becomes indestructible.

To make the attached save:

1. I placed everything in editor pause mode
2. unpaused
3. let the biter path through the wall to the turret
4. biter starts to attack the wall
5. Then I made the wall indestructible.
6. The biter continues to attack the wall, but does no damage any more

Thanks, fixed in 1.1.9.
