The position of vehicles in the Tech Tree has also changed after the update, however in the new Tree the positions of the KI-44-II hei and Ki-61-I ko in the Tech Tree Fold should be swapped. It is not appropriate to use the Ki-61-I-ko as a folding vehicle for the Ki-44-I, since in the Japanese text, the Ki-44 is a series, and the Ki-61 ko and otsu are a series.
And the text about the Ki-61 series appeared under the Chinese with the inscription Ki-100.
