I don't know if I stumbled upon on a trick, or it is just a weird behaviour. It is base fare related, no YQ there.

I found the following flights:

going out:
(city A)C2 - (city B)C4 - (city C)C4
coming back:
(city C)C4 - (city A)C2 - (city D)C2

Essentially an OJ flight that goes back through the point of origin. Weird part is that the base fares are listed on ITA as city A - city B going out and city B - city D coming back, even though there is an extra segment going out and city B is completely missing coming back!

The price is nice, because city C in C4 is usually more expensive then city B.

It priced out on O.

Edit:
Now thinking about it, it might be city A - city B going out
then city B-city C(long stopover)-city A-city D as a return. This way at least the base fares make sense, though it is still weird
