Windsor & Eton failed to close the gap at the top of the table after going down 2-1 at home against leaders Bashley.
Chris Knowles gave the visitors a second half lead with Matt Seedel levelling before Richard Gillespie hit the winner.
Both sides had early chances to get their sides ahead.
Bashley's Richard Gillespie almost capitalised on a mix-up between Sam Mazurek and Dave Tilbury and Ricci Dolan headed just wide at the other end.
Ben Porter sent an effort just over the bar and Mazurek did well to save Gillespie's close range effort.
Matt Seedel headed a James Edgerley corner just wide of the post as the half drew to a close.
It didn't take Bashley long after the re-start to take the lead.
Ryan Moss got down the left under pressure from Dave Tilbury, who was then pushed to the floor before Moss crossed for Chris Knowles to finish.
Bashley only managed to hold the lead for five minutes as Edgerley broke down the left and crossed for Seedel who made no mistake with his effort.
Into the last 10 minutes and Bashley grabbed the winner when Chris Ferrett's free kick was headed goalwards by Gillespie with the ball spinning up off a divert and over a diving Mazurek.
