There is also a “Re-number List” contextual menu command that appears when right-clicking on a selected list. In my experience it tends to not work as well as just toggling the list off and back on though, particularly where cut and paste has been used. I suspect doing that essentially creates its own self-contained list on the clipboard, so when you paste one list line into an existing list, you end up with three adjacent lists, and re-numbering will only work within the scope of one list at a time.
As for avoiding it, sometimes you won’t be able to, but if you are cutting and pasting mainly to move lines around within a list, check out the Edit ▸ Move ▸ Up|Down menu commands / keyboard shortcuts. That’s a lot easier than cutting and pasting in my opinion, and automatically renumbers as you move things around. They use the same shortcuts you would use to move binder items around in the sidebar as well as outliner & corkboard, as well, so you get to learn two very useful functions with one bout of memorisation.
