Rain being a douche

[FlawlessHappiness]

Could it be possible that the fog hid the rain? I don't see anything else that could cause this... or the particle system could be optimized so you had to be near to see it, I don't really know...

The fog cannot be hiding it. It's at a specific point that I'm unable to see it.

If I have the rain go through the ceiling, I can only see it if I face away from the windows.

I've set A to 500 so it should be easy to see. It's not just hard to see. It's literally gone.
