For some reason im getting a crash randomly as I explore, here is my crashlog
http://pastebin.com/qtXEYpMx

Not sure if this is a natura issue, CB issue or something completely unrelated

relevant information:
Minecraft version: 1.7.10
Forge: 1558
Nature: 1.7.10-2.2.1a2
Carpenter's Blocks: v3.3.7 - MC 1.7.10
client logfile: https://drive.google.com/file/d/0BwmxXoRAG3ddZUN6aHBJbnlQVmc/view?usp=sharing

If I can provide any additional information I'll be glad to get it together for you, thanks

Also posted on natura's board since I wasnt sure whats going on

Seems somehow side 6 (or base block) got passed as an argument to a texture method.. not sure how that happened, but I will look into it.
