Well this is again a game breaking bug...

Bug description: 

When you have the highest influence in a independent state (in my case 54%)  and one AI player has also a lot (lets say 38%).

When you start attacking that independent peoples city (to take them over and you lose all your influce) then the AI gets more than 60% that allows them to 

take over the city state. 

So the fight starts, with the "independent" people who now turn as you deploy your troops to a city belonging to the AI ( because they take over) 

and you cant begin the battle because you are not at "war" with that nation. You can also not end it. 

After saving and reloading you get the following error as well and the save game is corrupt (not loadable):

The operation was canceled.

Steps to reproduce:

So to explain it a little bit better: 

1. Load the game Round 191 Bevor Bug
2. Go to the city Maghas

1. You will see 3 units of mine being left side of the city
2. Attack the city Maghas to take it over
3. Bug? [The city gets taken over by the AI]

First Bug:

1. Start the battle
2. Deploy the trops manually
3. Bug: Battle does not start 

Second Bug: 

1. Make the battle automatically
2. You end up in a situation where you conquered a city of someone else while not being in war with them, even better, i am still in an alliance with the player....

Expected behavior:

First Bug: 

Don't know? Is the battle then a patt, should the battle start? Is it a lost battle? Do you go to war with your ally?

Second Bug: 

I dont think I should be able to conquer a city that another nation owns when i am not at war with them?
