Okay a couple of things.
First of all the maps of item frames are now screen in splitscreen multi-player. Haven't tried in single player. It looks like all maps are added to the one frame and it's glitching between them all.
Next thing. The map size is now 4x4 instead of 5x5? Was this a mistake or intended? If intended why were we not informed?
Maps in frames are all Fubar. Along with Portal fields displaying sideways.

The world size is the same - check you generated the largest world. I've double checked mine - new world, definitely 5x5
There must be something up with my game. I have now generated a total of 8 large worlds and they are all 4X4. I guess I'll have to uninstall and reinstall and see if it fixes the issue.
