A potentially costly slip from Celtic proved to be a mere warning, despite failing to find a way past Hibs.
Stalemate at Easter Road was followed by Rangers capitulating to draw with Motherwell at Ibrox, allowing Ange Postecoglou 's side to retain their three point advantage at the top of the Premiership.
Celtic have undoubtedly been off-colour in recent matches, tumbling out of the Europa Conference League with two defeats to Bodo/Glimt before Sunday's slog against Hibs.
But while they remain top of the pile, there's no harm in analysing where things could be better.
Here are five issues for the manager to address to stop the weekend blip becoming something else.
J-League fatigue?
Daizen Maeda looked destined to be an instant hit when he swept home just minutes into his Celtic debut after arriving to much excitement from Japan.
But the ensuing weeks have been a tad more difficult for the forward, despite a respectable goal return.
Maeda's all round play hasn't quite been at it and he's already starting to take some stick from Celtic fans, albeit a minority. But is it really a surprise he's not quite firing on all cylinders having just played a full season in the J-League?
The same, to a lesser extent at the moment, could be said of Reo Hatate, who burst onto the scene spectacularly but has levelled off in recent games.
If fatigue is playing a part, it's difficult to envisage a solution other than giving the players some time off, which Postecoglou obviously cannot afford to do.
Return hopes for David Turnbull and Kyogo Furuhashi could not be more timely.
Formulate a Plan B
The absence of Giorgos Giakoumakis at Easter Road didn't help in this regard, leaving Postecoglou without an option to change the focal point of his team's attack.
But the Celtic manager has been frank and forthright in emphasising that his team will only ever play one way.
This can be music to fans' ears when teams are on the end of a battering but it can become a hindrance when the route to goal is not so simple.
Celtic soldiered on and on in the same manner at Easter Road despite it being patently obvious what they were doing was not working.
That being said, Postecoglou's system has already shown to be highly effective in the majority of games and has served up some sumptuous football.
But a hint of a Plan B when things aren't going to plan isn't a betrayal of his philosophy.
Left-back consistency
It's been an issue all season and perhaps one that cannot be properly addressed until the summer.
Postecoglou has chopped and changed regularly at left-back, with Greg Taylor, Josip Juranovic, Liam Scales, Adam Montgomery and even Boli Bolingoli getting a run-out in the position this season.
Anthony Ralston on the right and Juranovic on the left has been a mooted solution but Juranovic is also Celtic's best right-back and Postecoglou seems to prefer playing him there.
Scales has flitted in and out and a ropey display away at Bodo/Glimt suggests he's not yet ready to be the permanent solution.
Finding a settled option for that flank certainly wouldn't go amiss at the moment.
Get Jota firing again
The Portuguese roared back from injury at the turn of the year and helped tear Rangers apart but he hasn't carried that same spark in recent games.
He was poor at home to Bodo/Glimt then looked off the boil again as Celtic laboured in Edinburgh on Sunday.
This isn't so much a glaring issue with the player himself, to be fair.
At just 22 and playing a role whereby there is heavy responsibility to consistently produce big moments, inconsistency in Jota 's game is to be expected.
The task then is to get the on-loan Benfica forward back to his best and keep him there.
He has the potential to be the difference between further blips or a surge towards the title.
Game-changers needed
Despite the performance falling flat in the face of Hibs' resistance, Celtic made only one sub in replacing Tom Rogic with Matt O'Riley.
That was despite having the likes of Ralston, James Forrest, Karamoko Dembele and Yosuke Ideguchi ready to go in reserve.
Having spent heavily on his squad, it's somewhat eyebrow raising that Postecoglou felt there were not more ways he could change Sunday's game from the bench.
Clearly Giakoumakis was a miss but it was, nonetheless, a strange way of managing the game.
Celtic will need everyone if they are to retake the title and it was puzzling to see Postecoglou not utilise his squad when it was clearly needed.
