An image speaks a thousand words. It's pretty dissapointing when you try to save someone and you get stopped by this. :-(

I had time to type the command three times, nothing...and I think it's clear she's bleeding. :-(

I was also attempting to drop my pack to no avail, though that may have been me typoing - I am fairly sure I typed /c drop_pack several times.

How do you save someone by yanking his pack?

To take healing from it to heal them if you do not have any yourself.
