I’m confused as if it’s just me that didn’t read it or see it somewhere but I was working on sally/yax disk and I got past chapter 5 but still no mission unlocked with them. I can’t progress further with out missions to level them up. Did the disk really get added to our server with no possible way to obtain it yet?
You need to lvl them up to lvl 6. Once that happens, they should have a mission.
Make you sure you look in nit starteable missions and specifically choose those two. Maybe they have a mission you didn’t notice.
