This was with:
Flow: 1650e76b25980112e9e5097c721d77e672501ae1 (from GuidedTour commit), which is on top of {55b5aa794fb4043e660d3a3a2a99859b1454354b}.
```
var_export( $wgFlowMigrateReferenceWiki );
false
```
I ran `vagrant git-update` (which includes update.php), and got the following errors.
Not sure if this would be an issue in production, or it's just because of the constant back and forth locally developing and testing this reference stuff.
