Why city cap penalty appears after start of war?

[SAS]

I have 6 of 6 available cities and no city cap penalty without war
after start of war city cap penalty starts to appear after several turns
and it became bigger with each turn although my city count remains the same
why?

After the war started you see like 6/3? Then 6/2 etc?

May be you are occupying something? 6/6 doesn't seem to be like out of City Cap.

hmm, yes, my units besiege several enemy cities at that time
so when my units is on the some enemy territory this is counts towards my city cap?
this is very strange

Do you mean when you capture a city and are deciding it's fate? It is yours during that period, if you assimilate you keep that added city, if you raze it then it doesn't...starting next turn.

no, I mean my units on not captured enemy city territory
seems like game adds such not captured cities to my city cap to calculate penalty for some reason
although counter still shows not exceeded cap
