Two issues with today's beta update:
First off, my power armor icon on my pipboy map has been replaced by a mountain. My player icon has been replaced by my old power armor icon. This is just annoying, not that big of a deal though.
Second, and this one is big, there's a hard crash to desktop whenever I pull up the Workshop menu. 100% reproduceable and happens to me with saves from my current playtime (2 days and change) as well as old saves with only 5 hours of playtime though.
I can fix both of them by removing the beta update, though, and I can flip back and forth between beta and non-beta and the problems will show up and go away again as I do that.
