Just the text says Box 7, it still got transfered to "your Box 8"
Your Box 8 is still "linked" as Box 7
Look --->
https://www.virtuadopt.com/pc/feed/44947/box7
The link says 7, but it is your Box 8
The "program" (do not know the right word): that creats the text "X got succesfully transfered to Box
7" seems to use the old box name.
I never move whole boxes, because of this issue - just every single Pokemon. Which is painful.
--- your boxorder --- (Link = Box name)
box 1 = Box 1
box 4 = Box 2
box 13 = Box 3
box 5 = Box 4
... and so on
So you should be able to recreate "wrong" messages (with each box) all the time, right?
