Place backpack in chest. (Empty or full does not matter)
Click backpack then click inventory to place backpack into it.
Your total weight carried will be double what it should be. In the included screenshots it goes from 300 the weight of the stone to 608 or (300+4)*2
Moving the backpack to a different slot restores the proper weight. Using Ctrl + Left Click to move the backpack from a chest to the inventory does not cause this.
FYI my carry capacity is increased by your PackHorse mod and is the only mod installed that I can imagine could be causing a conflict here since I haven't tested this with only the Backpack mod installed.
