This is more of a question than an issue actualy. I just finished a full playthough today and I think the story was really well written and the ending I got made me really emotional. I'm a bit confused though. Avoiding spoilers, I ended my story on Ellison but I didn't get one of the ending challenges for that planet. Did I get a bad ending by mistake? My team didn't die there and it didn't seem bad to me.
Hi hi! When this was reported, we went through and tested each ending with challenges to make sure that they were activating properly. They were, so our best guess was that you had found a non-challenge ending.
Recently, we discovered a bug where ending challenge states were not being saved if an ending was previously seen during the same play session (without closing the game), and we're wondering if maybe that was responsible for what you've experienced.
v2.11 has a fix if you'd like to try again!
