I can't seem to locate it right now, but I think I remember this might have something to do with the console being on for an extended period of time? Not sure.
When you have a moment, I suggest sending this info directly to Pipeworks (the console developers) here:
Terraria: Console & Mobile Bug Form
You probably won't get a response, but the development team reads over every bug report that comes in through that form.
I know that you are aware of this
@Rosterdam, but for others that may be stopping by and reading - as an aside on a different topic, in case you haven't heard, placing Item Frames or Target Dummies in your world will cause it to not launch anymore, so avoid those two things for now. Pipeworks has submitted the patch, we're waiting on Nintendo to approve it.
