i thought this was just me but a bunch of us in chat were having the same problem so it seems to be common...

my feed doesn't always work. It will fill up and the mouth will open and I press it and nothing happens. Yes, there are enemies around and it still doesn't happen. Some people think you have to be a certain distance away but i've had it work standing right on top of people. For me I'd say it doesn't work 10-25% of the time.
