When I put mine back in on the previous oil change I made it a point to put it back in with a short 1/2" drive ratchet wrench. I tightened then backed off with the same ratchet several times to the point I felt I could get it back off the next time. Well this oil change I used the same ratchet to get it off.....it would not budge I had to use a breaker bar to get it loose. Might be my imagination but I can conservatively say I have removed thousands of oil drain plugs on cars, trucks, tractors and aircraft engines both recip and jets. What it seemed to me as it tightened up a bit, due to thermal cycling, on itself over that oil change cycle.
