In chapter 41, Archibald was revealed to be the administrator of destiny, wherein the administrator of time is Irenea, who gained a double perspective. In chapter 43, the first panel stated that an unwritten rule was created due to an error in time. Since Irenea is time's administrator, maybe the "game" mistook her work break as an order that adds a rule in the world. I personally think that the unwritten rule was for Louise and Irenea's roles to be reversed; Louise in Irenea's role as a side character, and Irenea in Louise's role as the female lead. In other words, their fate to be switched.
When Edeet found out that Elios can reveal the fate of her son in the space the crystal/jewel created, she started working on another research for destiny and fate (this is how she found out about archibald being administrator). Once Elios was exposed to Rodion, he became the bearer, and we know that Elios can corrupt the bearer. Since Rodion is in a vulnerable state as shown in the past few chapters, I think that Elios is leaking / escaping from his grasp, therefore leading to everyone remembering what happened in their past lives (id like to think that Elios is one of the rare errors in the "game" that happens when time is reversed too much).
In conclusion, the characters started getting flashbacks of their past lives because of the exposure to Elios and the influence of the time administrator in the "game". ╥﹏╥
