Unable to upgrade units or make hand cannons

just played a 3v3 where I got to the imperial age and had 4k food/gold and the game would not allow me to upgrade knights to cavalier.

Same for hand cannons… I build a university, researched chemistry and was unable to make hand cannons. block was greyed out as if I did not have enough resources, but the numbers for the resources were white and not red. I lost the game because I couldnt make units or spend my resources effectively
