so i just deleted and recreated the collection and loaded in the same texture and commited and it worked. before, when it wasnt working, nothing was in the scene except an instance of the collection and a camera. the textures were in the root of the assets folder and the collection was in a folder called prefabs. the only things i did differently this time were that i didnt have an instance of the collection in the hierarchy and that all i did before i commited was load in the texture as a sprite (before i had made a spritesheet and loaded it in that way, made a bunch of sprites and gave one colliders and an anchor before i hit commit)
