Farnborough Town are still without a win in the Conference after putting on another poor display in front of their own supporters.
Tommy Taylor's men started like a train and looked like making it lucky 13, this being their 13th game of the season and an illusive win looking more likely by each game.
But Colin Addison's Forest Green battled back from going a goal down early on to ease their own early-season worries.
Taylor however will be left to rue a number of missed chances in the opening half hour and indeed the loss of striker Andre Fashanu on the stroke of half time.
The on-loan hitman from Reading opened the scoring with a scorching volley from Sacha Opinel's cross on 12 minutes, but he then suffered an horrific broken leg just prior to the interval which reduced Cherrywood Road to silence.
In between however Forest Green had pegged back the Boro lead when Carl Hutchings netted a bizarre own goal from Steve Brodie's cross.
With heads still down from Fashanu's demise, the visitors capitalised and Brodie hammered home a header at the far post, this eight minutes into stoppage time.
Referee Rob Lee had already brandished four extremely harsh Farnborough yellow cards and the hosts were walking a tightrope, desperate not to add to their tally of five red cards so far this season.
But to Taylors horror they were unable to do so, Pat Sappleton received two bookings in the space of four minutes prior to the hour mark for fouls on Neil Grayson, leaving Boro having to battle with ten men yet again.
Forest Green, with everything seemingly going their way, punished them yet again when the immense Grayson nodded down a right-sided cross and Richard Kennedy fired home the third goal at the far post.
Boro however never stopped running and might have even stolen a point despite their poor second-half showing.
Sub Paul Harkness first missed an open goal from Ali Chaaban's cut-back and then rifled against the post when latching on to Opinel's long throw.
