I attached to the gist a 4th file that holds all the output from my console. During the session, I launch the game, create a new creative world, open the inventory to grab a coral Nerco Block, and place it.
Here the gist: http://gist.github.com/ajman1101/d02d2bdc755622273af115e44e028237
I only have an error at startup of a Minecraft world, which I attribute to loading in the whole world, the engine getting behind throwing some errors, then catching up with itself.
Do you see anything out of the ordinary N247S?
Thanks for your help so far as well!
