[GAMEPLAY] Lux models not rendering, framerate loss

Playing a standard 5v5 on SR today, I encountered a bug regarding Lux. Whenever the enemy team's Lux was visible (i.e., not hidden by fog of war) my frame rate dropped significantly. Roughly, the game "froze" for ~3/4 of a second every four or five game tics. As an Ezreal ADC, you can imagine this was very frustrating as it prevented 90% of my skillshots and farming. Other players in the match did not indicate a similar issue. It has only occurred once, and only since the latest update.

The game was NA Region, 28th of May, 2PM CT.
