For some reason now, whenever I save and load/restore my game, my position on the map moves down and to the right fairly significantly. At first I didn't really notice it walking around outside, but a few times now it has started getting me stuck in a wall which makes the save slot useless. I do use multiple saves, but I cycle through them and apparently it is now happening on all of my save slots. I tried starting a new game and the bug goes away - so it does appear to be associated with my save files. Any hope of fixing this without starting a new game?
