Camp Drybone Rain Showing through Walls

When it rains at Camp Drybone (Eastern Thanalan, Ul'dah), I've noticed that the rain "splatters" (animations when it hits the ground) go through the town building walls. I don't have a screen shot but reproducing this is easy:

1. Go inside the "Church of Saint Adama Landama" when it is raining hard (at an angle) in Camp Drybone (which it often is despite the name!).

2. Notice that the puddle effects are showing through the walls.

3. Repeat the same in any building in Camp Drybone and look at the wall with the door leading outside and you'll see the same effect.

This probably isn't a bug, just the wall design is thin enough that the graphic shows through. More of not-so-great design versus anything amiss with the game engine, and probably not worth worrying about epecially with content this old. But I saw it, so I'm reporting it. If not a bug, just throw in Not a Bug or Working as Intended and ignore me! Thanks.
