Hi Stabbey,
thanks for all the feedback by the way.
For this particular issue in the buy menu:
could you provide a screenshot or way to repro, because on the current beta version it seems fine when having more than 8 units researched ?
The bug I was experiencing was in War Factories. I just played a quick campaign versus the AI, and I researched all the units, and was unable to reproduce the bug, I saw all the available units to produce.
