[0.10.12] Biters attack through walls

[Kirk]

Since I've updated to the latest stable (0.10.12) I've noticed even the small bitey-bites will attack things through one layer of wall.

I had a little trouble trying to get a biter to aggro on the turret, but the screenshot shows the turret losing health. I actually had this early game a lot until I decided to move my wall out one space.

Or at least, I'm assuming this is not supposed to be the case (last time I checked, only the big daddy biters could attack over walls).

Steps to reproduce:
- Built a turret.
- Build a wall directly around it with a thickness of only one tile.
- Get biter to aggro on the turret.
- Observe the turret losing health.

System:
Windows 7, 64 bit. Factorio 0.10.12, 64 bit.

Personally, I never understood the point to the mechanic anyway, since it's such a basic solution to avoid this special ability, and it's also counter-intuitive, making the game harder than it needs to be for new players.

I can't remember if it was like this with small biters or not before, it's been a while since I've played the older versions of the game, but I do remember the annoyance of biters being able to attack over walls.

In my opinion, it's a melee attack, they should be able to touch the object they're attacking to cause damage, in this case there's a wall in the way, so they should need to attack the wall first before they can attack the turret.

an easy solution though is to leave a 1 tile gap between the turret and the wall.

In my opinion, the devs should look at this and "fix" it, even if it isn't actually a bug.

The wiki explains that big biters can attack over walls, but it doesn't mention this ability for small or medium sized biters.
