Weapon Animation Mod Error? Glitch? Bug?

[Asharoth9029]

Good day everyone. I had facing a strange problem with my animation mod for weapon. So first, I had starting a new game 'cause I had installed new race to be used and had a typical problem of Helgen opening scene become buggy as always. Trying few times and finally everything goes to normal opening scene and safely going to Keep without CTD or anything.

However, after my tied hand is undone, I tried weapon to test and for strange reason the animation was broken. Like only certain animation played and not the basic nor heavy attack. I was worried so I check my older save and it was similar first before return to normal without problem.

Is this savefile faulty or there is some mod that might affect my newly created savegame's weapon animation?
