Server crashes upon starting with latest release

[imasonaz]

I had migrated to the first "release" for 1.3 (not beta), after migrating, I then updated to the latest version today to hopefully fix some issues with NPCs, quests, etc. Upon startup, I get the following:

[07/11/15 23:19:57] [Server API] Verbose: TerrariaApi - Server v1.19.0.0 started.
