This private build of the KOFXV edition select mod (https://gamebanana.com/mods/574428) has enabled advance strike and super loop Robert.
Advance strike was removed from the mod because the pre-advance strike characters will not have a dead input that nullifies other inputs.
When pre-advance strike characters have .5 meter and do 214CD, they will only walk back and block. This can last for several frames if CD is held after 214CD.
This can affect all neutral inputs that have 214C/D including hcb+C/D.
Go to timestamp 4:18 ( • KOFXV Edition Select Mod PS4 ) to see an example.
