Stock Koksan landing gear bug - 4.33u3 modless 64 bits, block 50.
I think it’s already known, maybe even folklore tile elevation (?) story, even though I couldn’t find much about it (Dee-Jay mentions it somewhere with a dose of uncertainty, April 2016).
The video is the reproduction of what happened exactly the same way on the same spot in the previous flight. The landing runway is 23L.
The runway is short, but leaving the runway on the previous taxiway (or shortening the flight before crossing that section) could be workarounds.
