"Rescue 50 friends" trophy broken?

[Zanreo]

So after playing some online, I noticed I had reached a bit over 50 rescues... yet, I did not get the "Low Fives" trophy for saving 50 friends (checked my trophy list too just in case because a few other trophies didn't show the notif when I got them for some reason). Thought it might possibly have been something about online messing up, so I tried a round with another controller (and got to grind out quite a few), and after going to the playlist after that, I saw I had reached over 100 rescues... checked trophy list again, and still no trophy. Is this trophy just broken (and with that, possibly the 250 rescues one too?) or is there something I'm missing here?

...nevermind, just had the trophy pop after finishing a Challenge level (as singleplayer) so guess it might just be delayed at times
