City produses after being burned

[grg121]

I am playing a single game (single 36455). An opponent has burned one of my cities, but the city continues to produce armies! (every two turns a unit of heavy infantry)

Hello, which city is it that prodcues troops?

[grg121]

Hi. It is Agartha. There is a unit of heavy cavalry standing on it

[grg121]

I do not mind finishing the game, if someone else should play in my place in order to see what's going on

[SnotlinG]

Yes I see something strange has happened to this city.
Could you describe the order things happened in.
I.e. who owned it? (Looks like an AI has owned it at some point?)
I see it is razed, and that it lastly was owned by you. Did you raze it yourself or did AI raze it?

[SnotlinG]

I have stopped that production now, you can continue the game if you like

[SnotlinG]

When the AI did his turn (and razed your city) I guess you had the client opened and watched his turn?
Did you see the city gets razed? Did you have that city (or any city) open at that time?

[grg121]

I show him raze the city. I didn't have any city open, I was just watching his visible moves and waiting for my turn

[SnotlinG]

Ok, do you remember if you somehow managed to open that city or not?
Did you have any vectoring to/from that city?

[grg121]

I only openned the city when I first conquered it, after pillaging, and chose to produce heavy infantry. I didn't have any vectoring to or from that city. I didn't open it either after it was razed, as it didn't exist and I didn't intend to rebuild it. When I show the first unit of heavy cavalry on it I thought may be I had put it there, though it didn't make any sense. I moved it and show later another unit of heavy cavalry on the city
