You are, I think, the 3rd player to be baffled by this encumbrance problem. I think at least one of them figured it out, but I'm afraid I don't know off-hand. The good news until that gets sorted out is that I find tracking encumbrance tedious and don't plan to make a big fuss about it. But hopefully one of the other players (likely Sirkov or Mane) will be of some assistance.
