Yuumi Q

Yuumi's Q - Prowling Projectile has a few issues. Easily reproduced at 100% rate by playing Yuumi and casting Q.

While attached, it shows the straight unattached indicator instead of the ring. The ring becomes visible only after casting, with the missile already in flight.

Secondly, the mana cost is bugged. Unattached, the amount of mana consumed matches the tooltip. But when attached, it costs double the tooltip amount.

Also, I'm not sure if it's intentional or not, but it requires a click to cast that it didn't before. Like before you could press Q while attached and it would just go, but now you have to press Q and then click what direction you want it to start. Based on the verbiage in the patch notes, I thought the only difference was that it was just going to be correctly launching in the direction of the cursor when you press Q. If it's intentional, no big deal, I can learn to adjust, but just wanted to bring it to your attention if it's not.
