Two sets of dual light switches control two lights at the top and bottom of my staircase. One switch on each set stopped working, why and how can I fix it?

Last night before going to bed I flicked the switch to turn off the light at the bottom of the staircase. Only I accidentally flicked the switch for the light at the top of the stairs and saw a spark which I thought came from the light bulb. I figured the bulb had burnt out because the switch no longer activated the light. This sucks because I'd need a ladder to reach it, which I don't have. Next morning my partner gets up first and finds that the light at the top of the stairs can still be turned on by the switch at the bottom. So now the current status is that there is one working switch at each end of the staircase controlling one light each, where there used to be two switches at each end controlling both lights.
So my questions are: what happened, how can I fix it, and how did the darn thing work to begin with?
