Events at Woodlands arguably made newly promoted Lymm's dramatic victory over Fylde the standout result of the weekend.
A Nev Edwards try nine minutes from time saw Sale FC edge Blackheath 19-14 to clinch a first win of the season.
Last year's runners-up entered the weekend off the back of four straight losses but Johnathan Keep's side were able to conclude September with a victory.
Tom Walsh scooted over to make it 7-0 but three penalties - two from Tom Ffitch and one from Matt Dalrymple - gave Blackheath a 9-5 half-time lead in challenging weather conditions at Heywood Road.
Rikki Stout scored a converted try to move Sale ahead but Leo Fielding went over just after the hour to restore 'Club's' advantage.
However, it was back to the winners' lounge for Sale as Edwards slid into the corner in the final 10 minutes to secure a welcome victory for the North-West outfit.
