Cut (cmd+x) doesn't work in G4

Glyphs
1

It acts like Copy right now. It does copy the shape but the shape doesn’t disappear after using Cut

What version do you have?
What are you trying to cut?

3

Latest version of G4. Any shape

4

You mean version 4.0.1 (4004)?

Yes. It’s suddenly working. I’m trying to figure out if there’s a pattern.
When it wasn’t working I tried to open the file with G3 and it worked.

Okay, I understand the bug pattern. It happens when I try to cut something from a layer that is not the master layer (copy layer)

That works for me, too.
