Mia's room is obvious bug, will fix, same with me missing the prologue text. Lingering screen tint is more mysterious because as you said, sometimes it happen, sometimes it doesn't happen, and I honestly don't know why, had the same issue during my playtesting, but hoped it's just MTool acting out. Will try and brute force it somehow I guess.
Roomba task is supposed to respawn for now simply because it's one of like 3 activities avalaible, I don't want to make map any emptier than it already is, once I add more stuff it will be set as a one-time quest. Overall, I will post a quick fix either today or tomorrow, waiting whether any other bugs get reported. Edit: I didn't get any other bug reports for now, and I'm busy af coz holidays, since they aren't game breaking patch is coming out after Christmas, have a Merry one and log off.
As for the schedule, it's as much for the followers as it is for me, if I don't set myself deadlines I will never realistically finish it, so I will still try my best to stick to what I set for myself.
