Yeah for me movement is restricted on Peragus while playing T3 after combat, only with T3. I then have to save and reload and then it works fine. I'm assuming it's because I have the T3 HD mod, or an issue with Darker Peragus. Not too sure, but after playing T3 and going back to the exile everything seems to be fine.
I shall let you know if it happens again with any other character, blaster or melee etc.
