Not sure if this is limited to equippable items only, but I have the movespeed bonus from equipping the item.  After an encounter, the bonus is gone.  I need to re-equip the item for the bonus to appear again.

 

Edit: nope, not limited to equipped items.  The Fast Runner talent also resets after the first combat, making its movespeed bonus not work.

I'm also getting a lot of problems with movespeed being broken.

 

My main character barbarian is permanently slowed to a snail's pace in combat and in stealth.  My cipher is permanently on crack.  Too bad she's not a melee character.
