Bug 6man party Einhar's Memory of Harvest Beasts

Hi I was doing memory with my friends.
We do all 3 maps and kill 5 harvest beasts.

I was the host and i can`t find beast in captured. I got all best what my mates give me but still i can`t find them.

I had full beasts cap, but still that should free old one and give new one.

Can someone explain what happens?
