I'm sure we're all familiar with the way you click to move and can't, when there's something underfoot. This most commonly happens in the dark. Well, it's broad daylight, I'm standing in an open plain, and I can only move in some directions - mostly to my left. Going upward is the worst. At this point I can go down, and left - and back to the places I hung up. But it's not just one place - I've hit it repeatedly since I walked into one particular forest and killed a deer there. The only odd thing I've done tonight is play with :cam predict, in the hopes of having better luck seeing things I'm trying to chase. And I believe I logged out after my first such experiment; also I've now put the camera back to :cam border, which I believe to be the default I had had all along.
Needless to say the game is unplayable this way. And logging out and logging back in (where I logged out) did not help.
[Edit: relogging at my hearth fire cured it, I'm tempted to try walking in the same direction and see whether it happens again.]
[Edit: I took the same route and got the same problem. The location is above and to the left of Frank Caliendo's claim; hopefully that's enough information for the devs to find the spot.]
