The Stream Toy event had a bug in it when it was first added. If you used Scene Replay in the hut to watch it in the update it launched in, your game would be stuck in 'replay mode' and not update variables correctly in a lot of scenes. This has been fixed and you can get out of 'replay mode' by going to the hut and watching the Stream Toy scene one more time in any of the newer versions.
No luck, tried redoing the Stream scene in multiple different formats, and then redoing Maul's First and nothing changed. Even went back to an older save when meeting Maul for the first time, Stream scene, then working back to the Maul scene again. Nothing changed, my tents list still only has Orgram Groth and Korg
It turns out our fix somehow got reverted. Doing the Stream Scene from "Revisit Memories" will break your state in .84 again currently.Watching "Everett's Past" or "Wait for Shade" in the Revisit Memories menu will fix the bug though if you have those available. Just don't do the Stream one again for now. After that you should be able to go back to Iron Blood Battlegrounds and do the first time with Maul scene and have it update things correctly.
