Much-changed Eastbourne went down 50-5 at home to Folkestone, Matt Thompson scoring their try.
Among the various alterations forced upon the hosts was a third set of half backs in as many games.
Uckfield were 21-0 home winners over Betteshanger.
Lewes remain level on points with the leaders in London Three South East after their 8-7 verdict at home to Chichester.
Ben Polhill's try, converted by Steve Bradford, gave Chichester a first-half lead but Scott Patto's powerful 20-yard run and finish dragged Lewes back into the contest.
Huw James missed the simple conversion but made amends with a late penalty to settle what had become a bad-tempered contest.
Bognor's frustration goes on after a fifth successive narrow defeat, this time 23-20 at home to Tonbridge Juddian.
They were two points up when a visiting half back took a quick tap penalty late in the game and created the winning try.
Skipper Karl Flynn admitted: "It was devastating again. We're playing some great rugby."
If there was one failing in Bognor's game, it was slack defence which meant tries from Stuart Pearce (2) and Andy Shipp, plus a Rob Parry conversion and penalty, came to nothing.
Brighton went down 26-12 at home to high-flying Sevenoaks, Julian Hutchens scoring both tries and adding a conversion.
Skipper Andy Pinnock was encouraged, however.
He said: "We could have won the game."
