[1.05] Load crash and movement bugs

I seem to have a couple of rather annoying ones. First is my characters randomly deciding to go somewhere else when I right click on a place (what seems to happen is that they take one step in the right direction, then their destination changes to somewhere at the edge of the screen and off they go). The second bug is that when I try to load (say, when my character decides to randomly wander in front of an ogre), the game crashes - either during loading or whenever I try to do something afterwards. This happens every time I load unless I've just booted up the game. So every time I want to load, I need to quit and start it up again. Very, very annoying.

I'm running Vista 32-bit, with dual nVidia GeForce 8800 GT SLI (512MB each), with a PhysX adapter and ~3GB of RAM.

Anyone else having these problems?
