So be it. Yes I read it. It is fixed but as you say you have no idea why or how, you list the part replaced.
There is no way the engine will puke oil out from the filter housing if it has that top O-ring in place and the cap is fully tightened. The other O-rings obviously do their sealing but if that top O-ring is good and located correctly, oil (under pressure) is not getting past it.
In your case oil clearly came out of the filter housing.There are only 2 ways that can happen:
1 The O-ring is not there or severely damaged.
2 The black plastic filter cap is not fully threaded in and seated rendering that top O-ring useless.
I just changed the oil on my Crossfire about a month ago and as usual it takes forever to get that final 5mm of rotation to thread in against the seal of that top O-ring
