While trying to create a face by poly-modeling it, I realized one of the loops wasn't flowing in the right direction, and I can't understand why this is happening. There are adjacent loops that flow on the correct direction, but I probably messed around too much on this specific loop and now the flow is gone. Why is this happening and how to fix it?

This loop is flowing on the desired direction.

This is the loop with the wrong flow, the blue arrow is the desired direction.
