[GAMEPLAY] Yorick's corpse becomes terrain?!

Soooo I encountered this bug in a normal game in which i played Renekton and had just killed Yorick. His ult activated shortly before procd and we killed that one as well. So basically 's corpse became new terrain, which my team could not cross or stand on top. Testing in a custom game led to the result that Yorick's allies can still pass through the corpse but enemies can't. This bug seemingly only occurs when the "copy" of Yorick dies. I have not yet tested this bug in the scenario of Yorick ulting someone else, but I will leave a comment when I do.
