Thanks for letting me know.
My main difficulty with this bug is that I don't recall ever being able to produce it on my end. So, solving it will be tricky.
Jumping from character to character seems a bit different though, as that suggests the target is continually switching. While in the cases I've seen they are usually on the same targets but flashing.
I wonder if it has to do with continuing updating the target. (Thinking face)
In either case, the mystery is why it would be device/player specific.
