Bag despawned on server reconnect

[SirXen0]

Version: 0.9gbeta9 Reconnecting to the server caused the backpack to disappear, even though it still called the lines of "Joined EntityPlayer and Stored properties retrieved". This has only happened once and I can't reproduce it. Video: https://youtu.be/xuD0qR4GiGk

RIP tinkers tools in backpack.
