[Issue] "Invalid Target" for ground targeting actions do not fail stack

[DenL]

I had ground targeting spells set to use [Target] as target so I don't have to worry about aiming it.
Sometimes when a boss is outside the arena, the action will fail as "invalid target", but this would not fall back to normal targeting (using ground targeting), causing action to be unable to execute.
Would be great if this can be fixed, thanks!
