Regina wasn't affected by the curse. She retained her memories and everything. The town line was only meant for those that were cursed.

The other stuff like why Emma could find the town or August could find the town I have no idea. Maybe because Rumple made Emma the savior that is why she could find the town but as far as August I have no idea.
