Experienced this myself with a new game I’ve launched recently + a few of my other projects as well. Released a new game, it was growing more and more every day and even reached 660 CCU - and then the next day it dropped to ~200 and it’s been decreasing in terms of visits, CCU and revenue ever since.
No complaints from players, we didn’t release any updates/do any changes either. The game’s fall seems to have happened at the same time as the touched events breaking but I’m not sure if that’s just a coincidence.
What I’ve noticed is that Roblox has been making these algorithm changes multiple times over the last year. One of my games randomly spiked from 80 CCU to 500 about 5 times already, it’s almost like it’s in “waves”???
