Default Crack inside lens

I just dropped my canon 50mm 1.8. I've noticed a possible crack inside the lens yet its working completely fine. I want opinions on whether the crack can get worse.

Here's a picture.

The crack can't ever be in focus, and it's too far away from the objective element to cause much flare, so it probably won't affect image quality any worse than it is now. Cracks like this only get worse if the lens is contuinually stressed, such as when it's inside a metal mount that has bent. Since that lens has a plastic barrel, it wouldn't be permanently deformed so it's not continually stressing the lens, so the crack isn't likely to get any larger.

On the bright side, the 50mm f1.8 is the least expensive Canon lens. It might be cheaper to buy another one than getting it fixed out of warranty. Not sure if warranty covers non-manufacturer defects.

Definitely cheaper to replace.
While I dont think it will get any worse as it looks like a chip there may be times when it affects images, particulary in bright light or stopped all the down on the aperture.
