First time this happened in either B I or B II:
Bopping along on level 2 in the mine, strength at 170, decided to save, whereupon strength suddenly only 150 and I am desperately overburdened! AACK
What just happened??? Is this a rare bug, or did the system hiccup?
Anyway, I'll have to go back and start again when I still had my full strength. Rats.
So, do you have a Savefile from before - when you had the 170 lbs carrying capacity; and after - when you were down to 150 lbs carrying capacity?
Because, if you have both, and you've confirmed that this is a bug, I'd be tempted to send BW both
of these Savefiles...
