Thank you for making me aware of this! I am currently out of town on a family emergency so I do not have access to the source files. But I will work on this once I get home in a few weeks! I apologize for the delay!
Alright, I need to fix my statement. While trying to implement other weapons now I have been slightly incorrect. Grid 5-7 are for bow, 8-10 are One-hand/shield, 11-13 are polearm. So it looks like just the one-handers(axe, sword, and wand) and the shields are off by one. so they should be in Grids 8, 9, and 10 and the ones in grid 8 should be in grid one. However I do have to ask if you system supports the "unsupported" files he has in his folders. Because the ones I have in grid 8 are the animations for the one-handers and shields to appear on the characters back while walking around and that was in the "unsupported" folder.
