Battering Ram

[Lithorn]

There was no decay, And a village claim protects against decay. Not sure where that came from? They we're at 100% HP the whole time when they just started to dissapear when the ram broke a wall section.

They are red because the ram almost destroyed that whole wall in one go, not from decay.

Walls that appear to be in good condition (same color as when you build them) are not always that. Try repairing some of the tiles along your wall that look like they don't need it.
