According to Theme Park ERT on YouTube:
"Tatsu's paint job has been paused temporarily due to a lot of the crew getting sick and them not having enough painters to continue efficiently. So, with the holidays coming up, they've decided to halt all work on it until the New Year. This is very unfortunate considering they were trying to meet a deadline, but the good news is that Tatsu will open today and remain open until the New Year. What are your thoughts on this?"
