Graphic arrows and tokens

[Jean le Chauve]

When a token blocks/is blocked and it dies, the arrow that indicates the blocking remais in the field.

Card creatures doesn't have this problem (because their goes to graveyard and would activate some code to delete the arrow, IMO. This code is not activated when the token dies)

EDIT:

That happens too when a card is exiled and bounce during combat, so the problem is a bit different.
