Rabun region here. This happens to me constantly. There are entire weeks go by that my 4 scav camps are constantly completing all available missions without seeing my YGL mission appearing at all.
I’ve messaged in-game support about it at least 3 times throughout this year, each time very stereotypically being told that I just have to keep completing missions - that they have absolutely no control over the frequency of missions appearing because it’s, guess what!, ALL RANDOM! LOL.
Just this tournament alone, I aborted 3 major / long-time missions that I really wanted to complete just so I could attempt aborting everything to refresh YGL, and guess what… I’m out of top 10 this event because it hasn’t appeared at all in my scav queue since the event began. Still won’t. But I would bet 9,000 coins that it’ll appear within 12 hours of the event ending - that happens at least once a month.
On the flip side, my Brantley region account has YGL available for coin refresh 99% of the time as soon as I claim a completed YGL mission. It makes no f***ing sense.
