When I select multiple layers in the Layer panel, and accidentally double click I get an error I can’t rename the layers because they are in use (which I did not want to do anyway)
But after Esc-ing all the errors, the selected layers are suddenly on root level instead of on the parent layers they used to be, and CTRL+Z does not undo this change.
You can of course imagine it’s quite a hassle to find out where the layers (with almost identical names) came from in a large file.
I assume this is a bug since changing names should not un-parent layers I’d think.
