What if a trading city flips back?

[Tatran]

Situation :
A captured city with 3 dyes in its radius.
The city has also a temple + library.
Total culture is also larger than the AIs culture.

I sold all the dyes and after a few turns the city
flips back to AI I'm still at war with.

What are the consequences?A reputation hit?

 

[Tomoyo]

Yes, I'm afraid.

Update

The deals were MA + dyes.
Next turn the city was recaptured.
It was still possible to make MA + dyes,BUT
turns later I couldn't sell resources for gold.
Well this is some inconsequence.

Another update

I'm totally confused now.
I went to war with the "betrayed" civ.(Sumeria)
I tried to make a MA+ dyes with another civ against them.
They refuse,next turn they accept MA + dyes.(Korea)
Another civ (England) won't accept any deal for dyes,
but after entering some gold of their total they accept
the deal.England is also at war with Sumeria.
Does the war against the "betrayed" civ make all deals possible?

 

[Tomoyo]

Yes.

Final update

Sumeria was eliminated.
I (Vikings) went also to war with Korea.
Same MA + dyes deals per turn.No problem.
Also sold resources for gold per turn.
Most of the time the other AIs were broke,
so I had to try every turn.
The AIs also didn't mention the betrayal any more.

A reputation hit,but no penalty.Strange.
