@Axey I think i do know. Because the game update to 1.4.13 but your version is 1.4.10. That why it's error since first fight.
BUT this is good opportunity because last 3 update, your mod can use only one time. BEFORE the mod can use for all fights. Butas i mention before, last 3 version i can use only the first fight after that the second fight will be terminated every time.
So you can try this because it happen since the very first fight on the new game.
THANK YOU VERY MUCH BRO.
Please revise the mod, pleaseee
