All of a sudden last night i started getting invalid shares on one card, Any reason why this might happen?

Your card overclocking settings was at the boundary values. Invalid shares - it’s a signal that you need to reduce the OC. Try start from -50 MHz from current values, if it’s not help then reduce at next -50MHz and so on
