Suddenly can't attack enemy territories HELP

[Ananik95]

So, I think I came to blows with a game-breaking bug. Playing as Kong Rong. Everything going fine. 150k gold in my treasury, 10k income. Beautiful.
Of course, as a governor, can't proclaim myself emperor. The other three kings are Liu Bei (my ally), Sun Jian and Gongsun Zan. I start a war with Sun Jian, start eating up his territory and going after his capital.
While this is happening, I seize the opportunity and capture the weakened Gongsun Zan capital, thereby declaring myself emperor.
However, from this moment onwards, I can't attack any more Sun Jian territories. The bug is extremely weird. Sun Jian pops up as an enemy faction both on the map and in the diplomacy panel. However, when I right-click to attack his settlements (and I was going to attack the capital) nothing happens. The armies simply stand still. No options pop up. Moreover, despite Sun Jian being my enemy, my armies count as trespassing (???).
Any suggestions? It's really sad to leave a fine campaing in its final stages without being able to complete it.

Perhaps you missed some diplomatic changes. While im not sure if throne contenders give in to vassalization, but you make it sound like he has been vassalized by your ally.

[Kaesoron]

sure he isn't a vassal?

[Ananik95]

100% sure he has not been vassalized, Liu Bei is still at was with him and he appears as a common enemy in the diplomacy panel. I'm really puzzled

Same Problem here. Only three fractions left and I am compete over powered but i am not able to attach armies oder other cities anymore, so there is no option to win the game or is there? Ad neither of the other two fractions is a vassel.

Sadly I found no fix and had to leave the campaign as it is. A shame, really

I have the same issue with Yuan Shu. Just one more bug to add list of bugs that haven't been fixed in this game.

This is a known bug. See https://forums.totalwar.com/discussion/246519/not-able-to-attack

There is the known bug above.

I know another simple solution is sometiimes you turn forced march on and then forget its on so you can no longer attack in that stance.

This has happened to me (I only noticed it since the first beta/update).

What worked for me is I made peace with the faction, and I could then attack them (while we were at peace) without declaring war again.

So if you can try making peace, once you have made peace, see if you can attack them.
