I was running from a bear when I climbed onto a rock to escape. The bear hit me, and I went down. My NPC companion revived me, but I couldn't move using the WASD keys. I could jump, attack, etc., but I couldn't move using the WASD keys. I used the stuck feature to move me near my current location and then to the closest respawn point, to no avail. Exiting to main menu and relogging fixed it.
