iggorbb,
I downloaded in the M&B Repository and had a look on the itemkinds lines you give.
I took only the axes and spears of the pack, and on the loading of the game its crashs with the warning "Error too many variations on mesh 98" . . . I had similar errors with other items of your pack when I tried install all items, but was able to correct finding the item in question and correcting the names that didn't had the " _ " between words on the name.
But this item in particular I can't find because I just have a number to identify. U could give a look on your itemkinds to help fix?
