If you load the included save.. you'll lose it too!
Something weird that happens simultaneously though. I previously had started Bolshoi Theater.. but it had stopped "production" to an earlier coastal flood -- after the 3M that caused Sydney Opera House to completely disappear (there's no obvious feedback from the map either, except for a newly submerged tile connected to the Ternate city).. i could restart BolShoi!.
