huNter flag evolution:
prntscr.com/1599hlq (Bosnian, 2018 and earlier)
prntscr.com/1599jn2 (Serbian, 2019)
prntscr.com/1599lv9 (Bosnian, 2020 and on)
huNter is Serbian by nationality (Bosnian Serb), born in Sarajevo (Bosnian capital) and afaik moved to Bijeljina (Serbian city in RS, BiH) where most of his family was at the time.
So, conclusion (I think) is that HLTV takes into consideration country of birth for the displayed flag, rather than nationality, which would make sense now that they changed mantuu's flag to the Polish one. Thoughts?
