I got this Liq Instinct. and the the top of the frame is flatter than most frames. and as i run my finger over the side of the frame, there i feel a bump on both side, uneven... the frame is new, so my guess its prolly broken. any thoughts? no pics, besides the pics cant show the little bump on the side of the frame. but i can clearly feel it. its at around 11 clock, the bump feels different on each side so i doubt its done un purpose.
