Mate, I'm so thankful for all the information from you people, thank you thank you thank you for your time. From the getgo I understood how Campo Grande was a part of Lisbon (and even before I asked this question here [which now I shouldn't have asked] I looked up and found out Campo Grande is now Alvalade basically). I shouldn't have asked this question here now I understand, since this is more of an issue of my government and no problem on the Portuguese side. If there's any info from me in Portuguese databases it's probably correct, and I don't doubt that. I am going to take action here. I will do option one.
I made no bitching comments about the Portuguese Republic, this whole mess was definitely caused by a Hungarian administration/translation issue. The Portuguese Republic is not wrong, the Hungarian is, and I know that. I'm not saying comments about how Portugal should work so it would benefit me. I'm just asking Portuguese people. I got my answer, and I'm respecting each wise comment and replying to it... What's the issue with that? I'm not trying to be toxic, especially not with a topic like this. Why would I be toxic? Sorry if I sounded toxic, I had no intentions.
