Witcher 3 Blood and Win3: 3D models corrupted?

I have encountered a few glitches:
1) many Beauclair guardsmen are holding an invisible pike/lance
2) one of the sail boats I found near a lake was a hull with a mess of intersecting polygons above.
3) A well I found very late in the game (with a certain Wolf ;-) is also a badly mangled mess of polygons.

Anyone else seen this? Restarting the game does not fix anything. I can play anyway, but it is a blemish on an otherwise excellent game. I had no such errors in the base game.

Blood & Wine seems rather buggy.

Neogaf has a thread about path 1.21 crashing the game and
a general issues thread.

Hm, I haven't experienced anything that bad - almost all my issue shave been model/lighting related. One time I meditated in front of an inn keep and when I woke up, the outside world had vanished and I was trapped in some weird internal limbo ;-) Fortunately I could just reload. But B&W definitely feels more buggy...hopefully they'll squash them soon....
