What does TW have against their original stone castles?

Some of their coolest castle designs seem to always get changed over time. Almost every castle in the game started out as a cool gray, white or black stone castle, then one by one got turned into a wooden fort or a concrete structure. Back during early access, Vladiv castle was this evil looking black stone fortress in the deep wintery mountains. Assaulting that fort in game was amazing. I just noticed that Ormanford Castle, one of my last hold outs for cool, classic castle design in an actual bottleneck, perfect spot for a fortress, has been changed in design and moved. Why do they do this? Anyone else feel like the older designs were better? I feel less impressed with myself for owning a wooden fortress over a stone one...
