I know that I might sound stupid, but I really need help.

Okay, I need to add two different libraries into my game, Wearables & also Pixie's Combat Library. I've put them on to my game before, and I've figured out how to use them, but since I restarted the game, I cannot find the folder that I'm supposed to put the libraries in to. So, what is the name of the folder where all of my libraries are supposed to go?

They go in the same folder where your game file is. They should be kept together. Each game has its own copy of its libraries.

Thank you.
