Hi,
This is a problem I got twice when updating NGUI, I did not see other posts mentionning it.
I have a few grids that I fill with instanciated prefabs of buttons. After the update, all those buttons are instanciated with a scale of (300,300,300) instead of (1,1,1).
I am not sure what causes this, the prefabs are fine as well as the rest of the widgets. I guess i will fix it by forcing the scale of the buttons manually after the instanciation...
(Edit: after debugging a bit, I noticed the scale change occurs after I set the parents to the button:
ButtonTexture.transform.parent = m_GridTextures.transform;
-> ButtonTexture.transform.localScale goes from (1,1,1) to (300,300,300)
I don't know enough about unity yet to understand why this happens though...)
