Can't really describe it any better than that.
This image is without any PSG, 250 bulk. With one PSG it goes up to 291.
With 5 PSGs it goes up to 611.
But then I drop the PSG, and my bulk is now at 520.
I should stop posting issues for the foreseeable future, because this is the second time today I've had an issue either completely vanish out of nowhere or turn out to be stupidity on my part. I only just realized it was stuffing the batteries in my pockets.
