Material building contribution bug

When i am attempting to upgrade any building to level 3, the game lets me add the iron and clay etc. but then doesn’t do anything when i select the contribute part, the game doesn’t fully freeze but i get no more input from the joypad and can’t click off the menu with the m+k either and have to close the game by Win + click or alt tabbing out - did it 4 times now and nothing. Thought it may be limitation to upgrade but the buildings are only at level 2 :man_shrugging:
