Anti-Sway Broken--How Serious? Need Help!

I made my first emergency maneuver in 37+ years of travel trailer towing during my last trip. Someone had lost several foot long 6" X 6' timbers in my lane and I instinctively made two quick jerks of the wheel to thread myself through them without thinking about the trailer being there. The trailer reacted with a slight wag to the left and straightened right out. I tow a Nash 23F with a dodge 1500 big horn with a 1000 pound hitch with round bars and a single friction bar sway control. My hitch is adjusted properly as is the sway control. I am meticulous about tire pressures and lug nut torque. I believe the sway bar saved me from having to deal with my trailer reacting more or me losing control after the maneuver. Some posters believe these things have no effect but I beg to differ. Sway control was recommended to me in 1980, six trailers ago, by experienced RVers and I believe that was solid advice.
