Strange behavior with Blind/Buried vias

[schrodinger]

I have a 6x6 BGA that I have in my design that I am trying to place vias in pads to internal layers. I have succesfully done this before on an older version of pcbnew, but this time every time I try to place my via with the footprint associated in the netlist the via jumps around everywhere as if the software is trying to route around something. However if I add the same footprint into the layout outside of the netlist I am able to do everything without a hitch.

Attached is a gif demonstrating this behavior.

The light gray circle around your via is the required clearance (as set in your netclass) You will notice that it can not fit nearer as there are pads that have a different net assigned.
