4.2.1 update broke my project; MyCharacter.uasset not visible in Content Browser. How do I fix this or revert to 4.2.0?

Naturally I warned everyone I knew about the problem (and inability to rollback) as soon as it happened but I’ll let you know if I hear anything. Hope that the cause is found and that something can be done. Thank you once again for your attention, its reassuring that things are being looked into so quickly!
