why does riot never inform people of what the bugs that get champions disabled were?

Like the new Sion "bug" i played with a Sion literally a few hours before never saw a bug of any kind then all of a sudden someone found a bug wtf is the bug its not like telling people the bug is gonna cause a problem you already showed your PBE is incompetent at finding these bugs due to there being nobody in the PBE and we obviously can't use it since your removing it hence sion's disable maybe its just me but in a game that wont even let skins be your characters portraits in game cus its so into that stupid thing they call "clarity" they seem to like to keep a lot of crap about the game under wraps when it makes them look bad
