another 'is this a bug?'

[cthom]

i was desperate to get hold of oil because i had none in my territory. my culture was slowly eating towards an oil tile, though. then i'm given a quest by my generals to declare war and capture the city controlling the oil. i didn't want to do that, so i let the culture eventually swallow the tile. a pop-up screen then congratulated me on my 'greed' and my 'capture' of the city which remained in sumerian hands.

the text is probably off, the event itself wants you to capture a certain resource you are missing not a specific city so it works as designed
edit: the texts are

<English>
Greed[PARAGRAPH:1]You are tasked by your military leaders to seize control of that resource.
</English>
<English>
[PARAGRAPH:1]To complete this quest, you must invade %s1_civ and gain control of the %s2_resource resource.[PARAGRAPH:1]You will fail this quest if a rival civilization captures the target city first, if the city is destroyed, or if %d3 turns pass without achieving the objective.
</English>

the second one says something about a target city, the first one does not at all, I'd say the text is off

it was the text that appeared when the tile passed into my hands that referred to a captured city. it probably doesn't take into account culture grabbing it.
