Capturing city from Phoenicia, keeps loyalty ability

[Haggbart]

I've noticed what I think is a bug, where you capture a city from Dido (also must be a coastal city from the same continent as her capital) and it will keep the Phoenicia ability of not losing loyalty. I suppose this is a bug, and not working as intented? Anyone else had this?

I play with a modified version of Dido all the time lately. That is a bug not working as intended, typical one. They probably already know about it, lets hope anyways.
