Forgot to mention, needs the latest hotfix.
I'll do that after the next VP installer releases. In the meantime, I sent a support ticket to Steam support about the Workshop situation. Not keeping my hopes up, but there's a small chance.
Just wanted to drop by that I've passed Enlightenment era now in my playthrough and everything seemed to be running smoothly and I didn't notice any bugs. It was cool to see some new designs/unit lines! Thanks for your work.
