Well, I kind of figured out what was making the wizard move in a checkmark formation in the air. In the past, I opened the wizard's MED file, and moved the wizard to a different location in relation to the center point, and saved it. That is when the checkmark formation in the air started occurring. I brought back the original MED file of the wizard into my game, without it being moved the different location in relation to the center point, and now the wizard moves fine without the check mark pattern in the air.
