benten93,
wdym "select" i don't see anything that says that lol

Hello (: for anyone who has their spine hierarchy undefined, where their chest needs to be mapped, the fix is quite simple. Click on the avatar you plan to upload, on the right tab AKA "inspector", click "select" (it'll be at the top). It'll open the prefab. Click select once more. In the same tab on the right side you're working with, you'll see 4 options, one being "rig". Click on rig. Click on configure which will be about halfway down. It'll open a Macy's looking mannequin with green dots all over. About 3 options down, you'll see the chest is not defined. Double click where it says "none". A window will pop up. Scroll down and double click chest. Now that it's defined, go back to the inspector with your body-rigging, scroll down, and click apply. Click done. Beyond that, it should be ready for upload. If you're looking to have it visualized for you, YouTube has this exact process. Just search the problem. Good luck! 🖤

I figured out the fix but I'm not sure how to explain it in words.
