Problem with "undo last action"

It happened to me a few times that Glyphs randomly “forgets” my last actions when I want to undo.
I cannot recognize any pattern to this bug.

I am using Version 2.5.2 (1186)

P.s. Will there be an update soon ? I am also having trouble with the shifted groundline.

Greetings, Pilz !

Known bugs and already discussed in other threads. Update is imminent.
