Somewhere along the way my PC Ranger's Bear pet started moving slower than everyone else in the party.  Its most notable out of combat, if the party is moving across a map he seems to move at about 50% of their speed.  It also affects combat too.

 

edit: It seems that my PC Ranger now moves about twice as fast as the rest of the party, with the bear moving half as fast as the rest of the party.  I do not have any movement speed gear equipped.

 

edit2: Seems related to Fast mode and Scouting mode.

You've been hit by a well known bug. I've written a program that fixes saves suffering from it, but it currently doesn't deal with PC animal companions. If you wish, post your latest save here, and optimally an earlier save (before the problem appeared). I'll repair your save manually and possibly gather enough data to add animal companion support to my fix.

This is fixed in the next patch, which may be released as soon as tomorrow or as late as Thursday.
