    I too have references in other scripts going missing when updating prefabs. Components randomly get new FileIDs for some reason according to my Git. This has happened since the beginning of new prefab workflows to the latest 2019 alpha13. Not sure if it's due to a faulty upgrade process but this has been project breaking for months and needs attention.
