Kumari Wing Cannons visuals not displaying

fleetcaptain5

While firing the Kumari Phaser Wing Cannons (the weapon that comes with the ship itself), the visuals aren't being shown. The weapon is firing and dealing damage, it's just that you cannot see it. This happens during normal firing, while using scatter volley and rapid fire, and when using the Wing Cannon Overload console. In all these cases, the visuals aren't showing.

Earlier this week they were just fine, so it must have happened after one of the maintenance rounds this week.
