I noticed in 3.4 that the visual style of Citadel Walls had been changed to match that of the generic stone wall, just with better stats. I decided to revert them to their 3.3 look by copypasting the relevant section from descr_walls across versions, and at least at a glance it seems to've worked; all the big cities like Minas Ithil, Dol Amroth, Annuminas, etc, have reverted to the taller wall models on the settlement viewer. It's even save-compatible.
I was just curious, to anyone familiar with modding walls, if there's any more to it than that? Descr_walls only seems to cover appearance + what kind of tower the wall requires to climb. Am I running the risk of things getting silly?
