A Thicket excav bug nekem is előjött, írják a bugot a wikin is.
"Upon arrival at Thicket Excavations, there seems to be a foglike low-res concrete-floor, hovering above most of the real surfaces, and it persists underwater. It is the high distance version of the model one should only see when the object is very far away. This manifests in that both the Sole Survivor and Sully Mathis wade knee-deep in concrete, Sully always hovers around the compressor/pump, before the Sole Survivor suddenly falls into the water or the access-way leading down into the excavation. The impact of this bug can be negated by restarting the game."
Lehet, hogy az unofficial fallout 4 patch (vagyis mod) javítja, de nem néztem pontosan utána.
