Maybe someone already mentioned it, but if not:

When selecting a character other than the party leader and casting a buff on someone, the whole party rearranges to stand behind the selected character, resulting in characters running around for no reason.

Suggestion: Program the "rearrangement" command after a new "go to" command is issued (when the user left clicks on the ground), so the party stays in place while buffing.

Not a big deal, but an extremely easy fix.
