Error of creation of groups in the editor.
- Create 144 groups
- Create one more group (mistake)
- Clean 4 groups
- Create 1 group - it is impossible to create (mistake)
- Clean 70 groups
- Add 70 groups, empty groups are created
Actions for the following attempt to create and clean groups
lead to an error of creation of groups or creates their empty. I didn't try it to do more long, than on video,
but also it is so visible that in a certain step, I lose opportunity to create more than 70 groups.
