Syncing animation with animated mesh

[ger4]

I'm trying my hand at an animation where a character "plays" with themselves using a set of anal beads I ported from fallout. Both the animation and the animated mesh export fine to the game, but while the sync up in blender, the are always de-synced in game.

 

If someone could help to find the correct export procedure to fix this, I would be very grateful.

 

Thankyou
