The new React-based Avatar Editor being rolled out immediately updates the user’s hex body colors with BrickColor colors when the page loads. This creates a hassle for users who prefer to use the website and has set non-BrickColor colors for their body colors with the app or with 3rd-party browser extensions.
Steps to Reproduce:
Visit Log in to Roblox if you are enrolled in the A/B experiment.
This was just fixed by them adding a variable for if the body colors were updated by the user. Now the entire page errors out with another issue, but the fix should be noticeable once the page is back working again.
