Hey I am new here and I wanted to say I've been having the lag problem myself, though not sure if its the same as the one talked about here. After doing some reading around the forums I saw something about the getting rid of the bags, so I dumped them in the nearest barrel and all my lag problems where gone. My game is the BWP with almost all the mods for the non-expert version installed and I am only in chapter 2 of BGT. Oh, and last thing is even when my bags where totally empty as long as they where in the inventory of one of my characters I had lag.
