    Still in 2021.1.1f1

    Adding a new tile locks the editor, forcing you to quit the Unity editor (it also prevents you from saving, which is kind of frustrating).
    It's almost impossible to use tile palettes/maps now unfortunately.

    Seems like I've encountered this in 2019.3.11f1

    Whenever I try to edit a tilemap now, it just hard locks my editor.
