devices unable to join hosted world

After my app crashed with an iPhone connected to my world, I restarted the app. I could go in my worlds fine but my brother can't join on his iPhone that was connected at the time of the crash.

What I expected to happen was...:
Me and my brother would resume playing together after an app crash on my (server) side.

What actually happened was...:
I could play fine on his worlds, but I showed up as a blank username in the worlds menu on his device and he was unable to join any of my worlds.

Steps to Reproduce:
1. Host a LAN server on a nexus 7
2. Join on an iPhone.
3. App crash on nexus 7 side with iPhone connected.
4. Reopen app, rehost any world on the nexus 7
5. IPhone as well as an iPad that was not connected are unable to join any world on the nexus 7.
