Pony Fantasy VI Remake

I did some tests, and I cant find why I got an AirAnchor and a Chainsaw from Trappers... At this point I think I have a mispatched something or I hit a rare bug

And for the mamoth, I kill S&S because now you have less HPs per level so every lvl... and that the problem too.
Mamoth in vanilla attack (Blizzard) around 62 HP and left Terra with 22 HP and the frame time to attack the (other) mamoth.
In FilFan6 Mamoth attack (Blizzard) damage a little above the HP that Twily have at that point killing she... and for some reasons always attack befter Twily but that last could just be RNG.
