I've seen a couple of bugs regarding rotation and scaling, however I don't think this aspect has been covered, apologies if it was.
If you add a token that is say 5x10 and then rotate it, it no longer snaps to the grid properly. Instead of occupying 2 squares, it will now occupy 6 by being smack in the middle of them.
Example:
1) Open a new board
2) search for a 5x10 token (eg search dire bear, take the one from Devin Night's Token Set)
-> the token is put on a 5x5 square
3) resize to 5x10
-> the token is now in proper proportions and fills 2 fields exactly
4) rotate the token by 90 degree
-> the token now is centered over 6 fields, rather than directly on two
Workaround: you can alt-move it to fit 2 squares again, but you'd have to do it for every move.
