Bug: Refer-a-Friend rewards disappear

Patch 5.4.7 has brought a lot of intentional changes, and a couple of things that seem unintentional. The level 90 boost appeared briefly with a very high price point between restarts, and now, as the patch goes live for real, it seems that all refer-a-friend mounts have been removed from players' mount panes.

So it seems the mounts will be returning to players as soon as the developers can work out this bug. We've also heard reports that players who logged out while flying on RAF mounts are falling to their deaths.

This appears to apply to the Rocket, the Nightwing and the Zhevra as well as any other rewards received from refer-a-friend. WoW Insider has all their Spectral mounts from the Scroll of Resurrection intact, so the bug with that is clearly not affecting everyone.
