28-Sept-2016 This, combined with a new import of the Reference Persona, fixes the critical bug discovered yesterday. It is important that you not use the broken imported Persona, so please view this video right away: https://cl.ly/0X381w2s190Q. If you have any questions or are in anyway unclear how to proceed after viewing that video, please reach me in Slack or via support.
To be clear, there is no requirement to use the new Reference Persona - it is only there if you want it - just don't use the broken one!
And one more special case! If you have made a copy of the broken Persona, it is of course also broken, and you'll need to delete the copy before the broken original. Here's a quick video showing what that looks like; https://cl.ly/2P0a320M3i1w.
And another problem! It's a pain, but it is a 30 second fix: https://cl.ly/2F1S0w002d1I
