Battle restarts after calling Yanfly's Party System Scene

Hey game makers! I apologise beforehand in case im posting this question on the wrong thread or something.. It's first post here.
I'm really stuck rn and I would apreciate some help. Probably just a rookie mistake...

I only have two plugins:
Yanfly's Party System which limits or increases my active party in battle and also allows me to call a Scene (Scene_Party) which lets me switch who is participating in battle in my party and who is not.

And McKathlin's Custom Game Over, which basically plays a Common Event right after I lose a Battle (doesn't end the battle) instead of going to the Game Over Scene.

Basically what I'm trying to acomplish is something similar to a Pokémon party system, where my battle party is limited to 1 (1 vs 1 battles) and when my actor dies it calls the Scene_Party instead of a Game Over and lets me choose another actor to fight.

All my common event does is call the Scene_Party (SceneManager.push(Scene_Party)) and it works just fine, except when I cancel or finish the changes to the party the battle begins from the start instead of continuing... Why is this happening??...

I can provide more info if needed, thank you for the attention.
