I just played through Morning Sun this past weekend. I won a major victory in the scenario concerning the Chinese winter offensive, and got a pop-up
saying the Imperial Command authorized one more battle, presumably Chongqing. I then got another pop-up indicating that the campaign was over.
So no Chongqing scenario, and the individual scenarios have not been unlocked. What gives? I posted about this in regular forum, but to no avail.

Non- Steam version, 2.2.5, level 2 difficulty.

Have you completed all the secondary objectives in the Nanning scenario? Prior to the Winter Offensive one.

Thanks for replying. Frankly, I don't remember at this point if I achieved all the secondary objectives. I probably didn't, but why would that matter?
I got a major victory in the winter offensive scenario with about ten turns still left.

Any thoughts?

You need to complete all the secondary objectives in Nanning to acquire access to Chonqing.
