Perfect, thanks for confirming! I'm going to try updating the app to clear the cache automatically if a build fails like this, that way it would have failed the first time still but would have starting working the next rebuild.
Oh, and I don't know if you're open to suggestions, but for the game I'm making, I want to be able to craft items from stuff in the player's inventory. I could probably find a way to do it myself, but I'd appreciate if there was a function built in for simplicity's sake.
