Description : 

I was building a wonder in the city of Carthage when it got attacked and conquered by my treacherous vassal. Once I took the city back the build order didn't restart. I couldn't order it again. No city can now build that wonder but I do still own the claim on it. 

Steps to reproduce :

Haven't tested it but I'd imagine anyone losing a territory currently working on a wonder would face the same problem.

Reproductability :

Like I said, I didn't try this bug on other wonders/campaigns. But I did reload a save before losing my city to recapture it and still couldn't keep building my wonder so 5/5 for me.

Expected Behavior :

I'd expect I could keep building my wonder and this is not intended ^^.

Attachments :

Circled in red in the screenshot is where the wonder was being built. In the city screen we can see that production didn't restart and it isn't present in the construction panel either.

Here are the save files. I lose my city at turn 96 with enough troops around to take it back by the next turn.
