If The Doorman hits you with Luggage Cart while you are in Goo Ball form, the camera will zoom in and not return to its original position. It will fix itself after Goo Ball ends.
I made a thread about this a few weeks back with video, but the thread is gone now? Continuing on yours since I searched it up and didn't want to make a new thread.
Bug description:
If you are in your ultimate goo ball, your camera zooms out. To help with movement. If you are however hit by Doorman's cart ability, your camera seems to reset to the typical distance. This results in a blocked view and the severity depends on how much your goo ball is expanded. You are 100% blinded the entire ultimate and cannot do anything to cancel it out.
