I am not sure if you actually read these as I have submitted a couple that have had no updates or comments so will try this last time to submit one but here goes:
I have died so many times in 0.63 due to the fact I was looting and had an object in my hands but no space for it in my inventory and I have been attacked. I have been unable to draw a weapon using hot keys as the object in your hands is not discarded and as you have no space in your inventory the item just stays in your hands and the hot key does not work. You then generally die. The only way around this is to go into your inventory and drag the item out of your hands but generally by the time you do this you die.
