I captured a Forbidden Palace

[obsolete]

Since when do we get to keep national-wonders that we capture?

I believe this bug slipped through because I captured the city through culture-flipping.

Alright, never mind I see now that getting a city through peace-ful methods allows funky stuff like this to happen. I guess it's not really a bug at all.

Peaceful transfer also means you can move national buildings around in MP game (assuming you trust someone enough to loan cities around).
