Tried exactly that just now. It is not working here. I'm just being told that I don't have enough source crystals, as Nageron and others describe.
can't reproduce. It works simply and every time here.
The one thing I did notice in your video that is different to what I saw (besides whether or not it works) is that you're dealing with level 11 characters, while I'm dealing with characters who are already level 20. Kryalis already suggested this might be the cause of why it's working for you but not for myself, Nageron et al.
