After playing a few games with the Gold Order Ki-84 i just noticed that it has the same drifting problem as the FW, although it is not as bad as the D-12 it is pretty noticeable when trying to aim the bombs.
Is the tech tree version the same? i ask because in the FW D-12 case the JV 44 (gold order variant) feel worse in terms of the bug compared to the tech tree one.
