So I should not try to leap over 2.12.x, since 2.13.3 is broken (for me) and there is no minor version fix beyond the paid support. (Yes, I want prime, but money isn't available.)
It looks like my path forward is to rollback, go to 2.12.x, then either go to 3.13.0, or jump up to 2.14.x? Since I can't get to 2.13..4 those would be my only ways to ensure ACEs would stay working throughout.
