Glacial Door + Augram Wall Health and visuals
I've noticed that when closing the glacial door combined with the Augram wall; its health pool remains unchanged and no visual change or health change with the combined wall, the door does indeed prevent passage however.
By comparison; a fully functioning door/wall combination. Walls here are replacement earth, 75 health sand blocks in this case.
Hrm. I can't replicate this in the internal version - in my case, augrum walls bordering fully frozen glacial doors turn into permafrost as intended.
