I use Yami's Invert Targets script in my game, and ran into a problem I have no idea what to do about (not being a scripter). It happens when an actor has more than one action per turn. For example, you choose to use an item, which is usually used on allies, on the enemy. The target is inverted, action 1 is confirmed. Then there is action 2, let's say you choose to guard. The result is that the item is not used on the enemy, but on an ally.

I tried various combinations, and it seems the second choice determines the outcome. So if I chose to use one item on enemy and one on user, the first was used on the first party member, and the second on the user. And if I chose one item on user and one on enemy, both went to the same enemy. Same happens with attack (and probably magic/special attacks, I haven't tried those).

Is there any way to remedy this? I'm not sure what other info might be relevant (maybe that I use Yami's Battle Symphony, I don't think I have any other scripts that would influence it). I understand that this might be a big ask, but maybe someone is familiar with the script, or had a similar problem in the past that they successfully dealt with and can help me. I would enormously appreciate that.
