As titled, this bug will auto-select a specific part in the studio viewport when you click while you have a UI element selected. Currently, this bug only occurs in place-specific games. This bug can not always be reproduced but this issue happens place-by-place, so it doesn’t remain like this in one game.

In the video, you can see me select a UI element and then re-select the viewport in studio to de-select all the frames so I can visually see what I am working on. The bug always targets the same part every time as seen in the video when I de-select the UI, it selects the same part titled “PART THATS CLICKED EVERY TIME”
What should occur is studio should “disconnect” selection from all UI elements and viewport instances unless otherwise selected.
