For the record, that problem cannot be fixed with 3dsmax, I spent the whole night reordering bones and relinking the whole thing. It's impossible to have a bone in the last place of the list while it's children still are in the middle, it just sounds too esoteric. That's simply devil's work... Or a coder's

. Anyway, seems like now it works fine thanks to the coding ability of ASk.
On the other hand I would like to hear a word from Raven's guys about that strange bone ordering contradiction, just for curiosity (I know curiosity killed the cat).
