to be honest this is the way I feel every single time a landed a seminole and any retractible gear airplane that I fly now. No landing is "uneventfull". Thats just somthing that was instilled in me from private pilot days. I'm not saying it wont happpen to me cuase in this business anything is possible. Look what happened to the Eagle guys up in Boston a few years back. like your landing, everything was telling you good to go, but I bet if you looked in the convex mirror (if your PA-44 had it) you wouldnt have seen the nose gear down and locked.
