Once again, I noticed that some titles have disappeared from my list and I have to add them again. At first, I thought it was maybe a movie double, but sometimes the whole dramas disappears. For example https://mydramalist.com/29271-hide-and-seek, i added almost 3 times, and today was another one. So i wonder, is it some bug in database/because of some removed doubles or something else is happening, that some titles, just ain't there, even if i added them to the list, previously. It's not some kind "bug" per se, in the meaning that it didn't simple added it and i see window with some "something went wrong" thing. I had them on my list, even update them, when they were airing. And then, after some time, they vanished from completed, and i found them again and must add them again. Any tips, what's happening?
