Yes, and Navi's 3-man core changed fron flamie, s1mple, and electronic (since 2017) to s1mple, electronic, and Boombl4 (since mid 2019). You can check Navi's profile too. All the ranking stats from before 2019 have been removed.
When s1mple joined in 2016, core was Zeus, Edward and Flamie (since 2015). When edward left in 2017, core became Zeus, Flamie, and s1mple (since 2016). When zeus left in 2019, core became flamie, s1mple, and electronic (since 2017). When flamie left in 2021 for now, core became s1mple, electronic, and boomich (since 2019). Now, for example, if boombl4 leaves, new core would be s1mple, electronic, and Perfecto (from 2020).
Similarly, Vitality's core changed from Zywoo, apex, and RpK, to zywoo, apex, and shox. So, Vitality lost 150 points as well, in the latest ranking update.
