I think this wigged out the code that assigns the initial debuffs, because whenever I was basically dead-center at the start of that phase, I would have to move firmly to one side (my debuff would usually swap and keep stacks, as you're describing) then scoot quickly to the opposite color to get it to register before the 5-stack could wipe me out. Sometimes the server tick was on my side, and it would correct before I died. More often... I'd just curse as I watched Naia crumple to the 5-stack debuff timing out.

Ever since I noticed that, though, I took care to stand just enough left or right to be completely on a single moon color, and I haven't had that issue since.

Which isn't to dismiss this as a bug - but if that also applies to you, it might be a user-end solution so you can still enjoy the content while the actual code bug is (hopefully) fixed.
I do distinctly recall being in the exact middle for this phase shift on purpose, because I wanted to be able to change sides as soon as possible. You describing what I did and getting a similar results me indicate what my problem was. I'll have to be more deliberate with being on one side for phase shift when I next get the chance, and see if that helps.
