Adding a polygon collider 2d on runtime via script is broken on builds
To reproduce:
1. Open attached project
2. Open scene "screen". It contains a sprite and a script that attaches a polygon collider 2d component. There is also a script that draws the outlines of the collider
3. Run the scene - the collider looks nice
4. Build and run - the collider is somewhat random and not like the sprite at all

Any traction on this? I am using Unity 4.5.2f1 and it is still a problem.

I am having this exact same problem, but the suggested fix/work around does not work.
I have my textures in a Resources folder.
I have them set to Texture type 'Advanced'.
I have Read/Write enabled.
When I load them dynamically when testing, they work great. When they load via a build (Web, x86, Mac OSX) they all generated a seemingly random off centre PolygonCollider2D mesh.
Here is a textures .meta file:

In order to generate a Sprite outline, the texture must be readable. Otherwise pixel data is pushed to GPU and discarded.
Set Read/Write Enable in the texture importer to fix this
