Well i was making my new awsome Direwolves Of The Islands map and then i exported it welp, guess what! I started making the Rar. file. So when that was done i wanted to tell the others it's done! Buuuut it didn't work, So i rememberd there cannot just CANNOT Be duplicate particles and i fixed the particles and checked if i have sky or Obeject duplicates and guess what! NOPE I didn't have any. So i started the game up, POOOF FeralHeart.exe has stopped working :/ And then i reinstalled EVERYTHING and after that i tried the game STILL nothing! Next i copyed the FeralHeart file to my Desktop,

There's also a possibility of there being double files in your sky folder, your my_object folder, in addition to your particle folder.
