If there are issues, I would take AS up on that offer!
This custom build stuff is a huge new feature for AS and I am sure that there are some hiccups. That's part of the reason that I am still at v5.24.
Update: There is some version level where AS said that installing a later version over a previous version was "safe". I don't remember when that was. I would uninstall any AS Perl versions. Then install v5.28 anew and see how that works?
