Bug - Epic Astro Story: Workers able to travel through single squarestructures, path not shown however

How to reproduce:
- Start a game
- Build a structure that requires a resource
- Build a path on either side
Description
Notice that the person working at the structure would enter from either side and exit from either side, however when you place a structure, the area that the worker can move does not show past the structure. Check screen shots for further details

Screenshots:



Personal Notes:

I've been playing a lot of IPhone games, in particular by Kariosoft. I have not seen any major issues, a couple of weird ones like small intermittent crashes that I can never reproduce or are due to some unknown error. But this looks like a path-ing (its a word!) issue.

When you select particular buildings it shows the range that the building has along the paths. However if there are things in the way, this generally means that the workers cant get past it either. However if the thing in the way is another structure, this makes things interesting. If the worker is currently working in the building or has something they want on the other side. They just walk straight through.

I would call this a minor bug. A graphical one at best. However I would call this an exploit ^_^
