No, we're not invading anyone, so calm down.
But it is completely unusable. We built it fine, about ten tiles from where it was needed. Glue dried next day. We tried to move it and within 3 tiles had broken. Repair, reglue, wait.
But by the time the glue dried THIS time, it had decayed. Repair, reglue, wait. (*)
(*) repeat this step for 3 days before entire village gets ill and nothing has still been battered.
I don't think that the ram is working right, because nobody could ever invade anyone unless they were away for a month; this may be intentional, but in a case of "oops too much wall" .... it is less "balancing" or "grief-reducing" and more "hair-pullingly irritating".
Possible Suggestion for Workaround: Allow the original builder of a palisade / wall (if that is recorded) to be able to destroy it (even if it takes ten pots of tea
