when prediction is enabled and scaffold fails to place a block, it will fallback to the predictions of the normal mode using ScaffoldNormalTechnique.getRotations(target). (even if its called getRotations the prediction doesn't actually get affected by the normal mode's rotations because of the CenterTargetPositionFactory setting - line 102)
when you test it check if you have ledge enabled before trying to use it without predictions, it never worked without it. and you need to have atleast a bit of pitch jitter so you dont fall with the predictions
