why is it so much easier to run with uke than with your own tori (only tested in single player)

when i start my run with my tori he's very unstable and already goes to the right on the first step, with uke i can start and run in a straight line

am i doing something wrong?

Probably.
You should ask some of the staff.
Maybe you need to go over the joints.

Well uke and tori werent built excatly the same for a specific reason, I dont really know but you would have to ask someone

problem seems to be fixed, it only seems to be occur on custom mods like parkourdream etc

Tori & Uke are slightly different due to balance & the slight difference in centre position.

Check the modding forum for info on it etc.
