Did I mess up with Scarlett?
Yes.
The chest spawns where the hologram was. The scarlet that goes to the door is a distraction and it worked =/

Yes, that chest was in the room when you defeated the hologram.
Yes. You can go through it again to get the chest. After beating the holograms, a chest will appear in the middle of the room while Scarlet hobbles away.
You also didn’t miss much. About 3 obby shards, some greens, and a chance at a rare or better.
is the chest a one time thing or does it reset every day? (nice way to get obsidian shard)
It is every fight with the hologram. No reset on the chest.
