the patch from yesterday caused this. this scenario only happened once. the other times the black shield worked fine. there was no other magic damage that could have broken the black shield....i'm 100% hook went straight through the black shield on its own. people in the game said morgana is bugged jsut thought i'd help sperad the word. fk typos
There's currently a bug with Morgana's Black Shield where, if a spell deals enough damage to break the shield, it'll then apply its CC to the target. In prior patches even a 1 health black shield would block the CC as the shield broke by contrast. We're working on a fix for that at the moment, it's definitely not an intended change.
Maybe Thresh had high AP? Do you have a match history?
Morgana's E has been bugged lately and I found her not being able to avoid silences either
