Anivia's Q aiming reticle is stuck

Smartcast and missile indicators for Q are stuck at absolute max range. I can pivot it as usual, but am unable to move the reticle in towards Anivia at all. This is not a problem with the Q, only the missile indicators are stuck.

Before the patch that fixed her walk-and-fire Q, I could fix this by toggling smartcast and firing a q before switching back to normal. This doesn't work anymore, and it's affecting both forms of Q aiming now.

This is incredibly distracting and frustrating. Please help!
