nope, can't fix that.
love emoji = your party member becomes zombie and fight for the opponent. since your hero is super strong, it will kill another hero with same team ofc. solution = disable mod when you get opponent with love emoji, or try to kill that love emoji opponent first before the love spell activated.
poison etc = no clue, that's part of the game, i didn't remove enemy skills/abilities, that's part of the game. You can't kill it, then even if you play original you will not be able to kill it. I suggest to level up but then I don't play the game, no clue
