apparently, niche has been struggling with buggy achievements for years now. personally, I was able to unlock all of them (I started playing some weeks ago), except for two: the "globetrotter" and "EmmaUniverse" ones. the former seems to be a very common problem, the latter one would not unlock for me even after breeding the required nicheling several times.
what can we do about this? if it's such a common issue, couldn't the requirements for them be changed or be turned into legacy achievements, so that those of us who are completionists don't have their stats ruined by an unsolvable error?
