[0.95.18] Disappearing Crafting Stations

My plate beating station, armor plate storage, and heavy armor crafting station have disappeared. I have tried loading up previous saves from when it still existed, but it isn't there, either and one worker keeps working on it

It's the plate beating station and armor smithy on top of the Y-building right next to the research lab
