I opened a new world, and went to go chop down a tree. When I got a log I opened my inventory to make some planks. i decided to use the recipe book feature. I accidentally clicked the new "Spruce Bark" as I hovered over it. It should be noted I was unable to make it as I only had one log. But I clicked it, and my game crashed. (I'd post a log file, but I don't know how to get to those.)
