"Healun'or" would be rightfully ours, if someone hadn't said they just gave it to us for OOC reasons.
Honestly, you're acting it was some irrelevant person making some dumb comment. But they were THE reason we got Haelun'or, without them it would have never happened.
So yes, it's a valid reason.
And let's be real: If Haelun'or is that irrelevant it will either:
a) get conquered in the next WC in 4 weeks.
b) die due activity and we take the city by buying the tile.
So for real, don't make a drama over nothing.
