Not sure if this was a bug or not, but im reporting it.
My character was hunting rothe, I encounter afew nasty monsters who procede to kick my ass :P I figured I better drop the meat and run, I drop the meat so I can run, I run afew feet and then im suddenly striken with weight gain and im heavy encumbered, naturally I died, Not sure if this is a bug report, but the units had NO ability drains so I have no idea where the extra weight came from -_-.
