I want to add animation frames to the sideview battlers on RPG Maker MZ.

When I setup the notetags on the actor like this:

Code:

<Sideview Battler: test_actor>
<Sideview Battler Frames: 30>
<Sideview Battler Speed: 5>
<Sideview Battler Size: 64, 64>

<Sideview Battler Motion>
Name: Wait
Index: 0
Loop
Frames: 3
Speed: 5
</Sideview Battler Motion>

and then enter a battle, the game crashes with this error:

JavaScript:

TypeError: Cannot read property 'index' of undefined

I have already tried using the FOSSIL compatibility plugin.
Feel free to suggest any plugin that enables adding more frames to the sideview battlers. I know of the "Dragonbones Union Plugin" but I really don't want to use Dragonbones since I just make my animations in Aseprite.

Thank you!
