Town boss Nathan Jones was disappointed to see his side concede early on again as they fell to a 2-1 defeat at Doncaster Rovers in Sky Bet League One this afternoon.
Donny took the lead six minutes in as Matty Blair was allowed space to run at goal and curl an effort into the top left corner, before Elliot Lee headed in from close range to equalise on the stroke of half-time.
The hosts came out and restored their lead just 35 seconds after the restart, as Ben Whiteman's deflected effort beat James Shea.
The result sees the Hatters remain in the top half of the table, sitting in 11th with eight points after seven games.
Jones said: "We keep saying it. We're controlling games, we were pretty dominant first half. We started the second poorly. We work on starts, we work on what we have got to do, maybe we shouldn't, maybe we should just let them get on with it.
"After the goal I thought were excellent, chance after chance, opportunity after opportunity. We controlled the game. these are a very good footballing side, all our reports came back and we were watching games, they cause sides real, real problems.
"We caused all the problems, they changed their shape at half-time, we come in at half-time right after scoring, thinking all the momentum is with us. One ball into the box, it's not even a good ball into the box and our six-foot left-back who is very good in the air doesn't win his header, it drops, we don't get on the second, we don't get on the third. Then you've got another mountain to climb.
"We're having to show a lot of character lately, but the reason we're having to show a lot of character is because we are giving goals away and it's poor. Our structure going forward, the way we play and how we cause problems is very good, it's excellent.
"But at the moment we're not keeping clean sheets and if you don't keep clean sheets then you don't win games."
