[Error] [Using v21] NoMethodError only occurring when in battle against a Simisear and Pignite

[EmoMickey49]

When I attempt to hit either of them with any move, I get these following errors:

[Pokémon Essentials version 21.1]

Am I getting two of these because there's two battlers? This wasn't happening in any other double battle I've had with all sorts of pokemon.

Here's a screenshot of the battle:



I have the plugins for v21.1 downloaded as well as the gen 9 pack.

I also just don't know how to interpret these messages to be honest :( could anyone help with that? Thank you so much!
