Two minutes of madness proved costly for the Hawks as they lost 2-1 to Bromley in the Blue Square South at Westleigh Park.
Hawks boss Shaun Gale was left fuming as his side threw away the lead, gifting the visitors two goals in as many minutes, early in the second half.
And, though his side laid seige to the Bromley goal for long spells, they failed to find a way back.
The defeat leaves Hawks in 18th place, just two points above the bottom three.
New striker Ollie Palmer had earlier scored his first for the goal club.
But after the defeat, Gale pointed to individual errors.
‘It’s back to where we were five games ago, with people making stupid mistakes,’ said Gale.
‘I can’t legislate for people keeping making silly errors.
‘It drives me mad as a manager.
‘We haven’t been undone by great skill, we have been undone by our own stupidity.
‘It was a gift and Bromley must have thought they had won the lottery.
‘I don’t know whether their first goal was offside or not but we made the wrong choices.
‘It is bitterly disappointing because I thought we played well.’
Bromley offered a threat throughout the contest, with their quick counter-attacks.
But the Hawks gained the upperhand, six minutes before the break, through Palmer’s goal.
A long throw from Jon McDonald was headed on by Lee Peacock and Palmer poked the ball home from close-range.
The Hawks made a confident start to the second half but things went quickly awry.
On 55 minutes, a long ball over the top left the home side appealing in vain for offside.
Gareth Williams was allowed to run on and set up Hakeem Araba for a simple finish.
Almost immediately, Hawks defender Sam Pearce was caught out trying to control a ball rather than clear.
The ball bounced away off his shin, allowing Araba to run on and fire into the roof of the net.
Gale introduced ex-Pompey star Vincent Pericard up front alongside Lee Peacock and Palmer but still they couldn’t get past Bromley’s brave rearguard action.
Gale added: ‘I thought it was even-stevens in the first 20 minutes but then we got our goal and were in control.
‘We looked comfortable and heading for three points but gave them something to hang on to.
‘They sat back and rode their luck a bit at the end when we went three up top but to their credit they made it difficult for us.
‘We are not in a position to be doing things like this and after 12 games, it is not ideal.
‘If people don’t stop making silly individual errors it will be down to me as manager to do something.
‘If they can’t do the job I will get someone in who can.’
