Without movig uke a kick that would lift him/push him in the direction I want him in wouldnt be possible, seeing as I kick him in the foot that is lowered because of the laxed ankle.

So a glitch that corrupts your replay, cannot be re-created in the same replays, makes it possible for the replay to exist and I agree with you that it may be something with light/small conections, sometimes maybe too small for TB to detect it. So TB does what it can to continue that replay, and then this happens.
