Some boss abilities not showing since latest patch 3.28.0h

I've been noticing boss abilities not showing such as when Veritania yells "I shall free you" and crashes onto the ground, the circle simply no longer appears. Same for the Searing Exarch when he casts Incineration, red expanding runes on the ground are supposed to appear but they no longer do. In his ball phase Maven also just looks completely bugged.
