Okay...

Sorry i didn't mean to just send that... i'm having a super annoying problem, when i hit ctrl+A then lock the scaling on the Y axis, for some reasons it scales my vertex on the Z axis... same goes for the X axis, if i hit X it scales on the Y axis... To be more precise, Blender knows i'm trying to scale on the Y axis or X, it displays the right color line, but still keeps scaling on the wrong axis...

For now the only bit of info i got from the web is that i might have rotated my model at the very beginning because i was making my character pointing the wrong way. since i've rotated the model, Blender is now confused wether i want to scale on the X Y or Z axis. I'll restart the whole thing and see if it's going better
