I was just solving my 5x5 cube as always, but at the end I got this configuration and haven't found anything regarding this kind of parity. I am pretty sure all squares are correctly placed and no twists are there.
Before I got the edge parity in 5x5, then I used my 4x4 parity algorithm taking 1-2 as left and right sides respectively. This was the result. I am pretty much confused to how this happened?
The configuration is:
whole solved except middle edges on O-Y, Y-R, R-W are y-r, w-r, o-y respectively with r-r-y on top(rotating ccw).
