Same issue happened to me.

Same here.
In single player it was once, when AI just couldnt move its unit to attack me, and he was simply stuck.
In multiplayer it occurs every 10 minutes, and we have to reload autosave. It seems like in multiplayer each battle has chance to have wrong control players, cuz some battles just finished automatically even if I didn't choose to end it like this, some battles are written "You are not participating here", but it's battle of MY army. And again you can't finish your turn in any way.

Also, in network play, when you are attacked by AI, battles are often completed automatically. AND 100 strength army against 90 strength army simply wins with NO losses even in health. And all you can do is just load autosave here. 60 turns game 2 ppl we already loaded like 15 times, it's insane to play like this ...

I noticed this thread is in "Bug Report Archives"
Probably is better to find a thread in "Bug Reports" to mention the issues.
I also noticed there are several posts regarding this bug mentioned.
Devs are aware of this bug and are working on it. Known issues page : Known Issues Page

Yup having exactly this problem...

I am also having this issue. It happens regularly enough even when the AI is thw aggressor. 

Same bug here !

I've got the same issue BUT managed to get a solution.

Stuck in battle. Solution:

1. Press the cross to go back to the world map.

2. Make a Save 

3. Load the recently made Save file 

4. Go back to the battle and watch the AI play his turn.

You're verry welcome :)

Solution not working for me. What i did notice is that the AI gave me a peace deal. 

The new BETA patch should fix some of these issues, so the best solution is to wait a bit.

Still facing this issue after the latest patch. This time, I had two battles initialized by AI in one round, and during the manual combat of one, the AI was stuck. The other manual battle went through and prompted me to wait end turn. But the stuck one couldn't be resolved without ending and reloading the previous save.

Yeah patch seems to have fixed for me... not seen since.

[PC/Steam, v.1.2.139] AI got stuck in battle.The bug still appears.

When I ended my turn in the battle, the AI made a few moves but then stoped and got stuck in battle because it stops making moves. I can't end the round becouse of the ongoing battle.

I tried reloading and restarting and played the battle diffrently but the AI just makes a few moves more or less and then gets stuck.

I don't think its important but I add a few Information about my game: Medieval Era / English / Round 99 / Map size idk / Fight animation tempo 1 / Singleplayer

I think the bug occurs when the AI has no attack oppurtunitys left and fails ending the battle turn.

The newest patch fixed the issue. Thank you very much :)

This is constantly happening to me and it is so infuriating :( The only way to *sometimes* fix it is save and reload and even then not always.  I have had to completely restart campaigns that just can't be played anymore because of this bug.

I had this happen today after the Nov 21 patch.  My turn in combat, moved a unit and then attacked with it and the battle stuck there with my unit 'thinking' about attacking.

December 2021 and this bug still happens.

That's sad, I bought this game 1 week ago and found a game-breaking bug.

so unfortunate. I tried different things, even going back a few saved games and didn't help.

I'm starting a new game but I hope this bug doesn't happen again.

December 6th and still have this issue on multiple unplayable campaigns. Rarely get to finish a long game because this issue will pop up and no matter how many times I reload the save a few turns back, the ai will attack me and get stuck on its turn. 

Same just happened to me, 06/03/22.

But yeah it just happened to me too so the bug is still in the game.
