Yes, I romance Caron and Sigolla and I get their hologram. I first killed Ouranos then with the replay function recruited him but it didn't help maybe it did something that broke the unlock code of this gallery? I am attaching an image with the only animation that I don't have, it seem to be Ouranos one. Thanks for trying to help me.
It's strange, the missing animations are sex animations for Ouranos and Zero. I checked the triggers inside their levels, they seem to be fine. I'll research this further, and you can click three times on Sigolla's boobs in the main menu of the game, it will unlock all animations and HCGs. I apologize for this bug, thanks for telling me about it!
