Models Shift Position when Changed

[Uncertain Title]

I created two walls: both have a base brush that is 128 x 128, and 4 units thick. 

One of the brushes, however, has a little bit of decor that sticks out another 4 units.

 

Later on when I was working on my map, I cloned a model, moved it 128 units, and then changed it's model. However, when changing it from the wall with decor to the wall with no decor, it proceeded to shift itself 2 units forward.

I thought maybe it had to do with what grid size I had saved/exported the model as, but adjusting that did nothing. And the models are both aligned together.

This is the only model I've had do this. What is causing this?

One of your walls has dimension 128x4x128, the other has dimensions 128x8x128

In other words, their origin points are at (64,2,64) and (64,4,64).

If their origins were at their, say, lower left corner it would all be fine but because by default they're at the center you get that seeming offset by 2.

That makes sense. I just don't get why it's happening now. This is my third batch of models and this hasn't happened before.

I appreciate the input though. Maybe I can add/adjust it in some way to make it not do this anymore.
