I'm not sure which is causing the issue, but it seems like whenever I pick up a big stack of berries and put them in my bag, the game thinks I can't move despite being barely over my weight limit and well under my encumbrance limit. On relog, I can move as expected, a bit slowly. The issue sometimes happens when putting things down, too. I haven't nailed down exactly what causes it, but my guess is something isn't updating when it should, like maybe the move into or out of a container?

Fixed.
