The Premium U-2 (Night Witches) squad and Yak-9K squad both display as a “Fighter pilot squad” in the squad filter, while being a “Assault pilot squad.”
I don’t know if this causes any actual issues in a match relating to the spawn limit of one fighter and one close attack plane. I know there were previous issues with the close attack P-38 seemingly occupying both slots at once.
This bug is already known. Hopefully it’s going to be fixed soon.
