Munster and Glasgow continued their march on the Pro12's top spot on Saturday, each winning their Irish encounters with the Red Army at home to Ospreys, while the Warriors triumphed on their trip to Ulster.
The pair continue to reign as the in-form sides of the division, but they now head into a November period where losing some of their bigger stars to the international cause could prove costly.
That being said, it was more than the summit of the table that shifted on Saturday as the likes of Cardiff Blues and Scarlets each experienced changes in their situations.
Cardiff Blues 17-13 Treviso
Making 10 changes from the side that was demolished by Ulster last weekend, Cardiff Blues bounced back with a hard-fought win over Benetton Treviso that didn't come without its share of scary moments.
Captain Josh Navidi contributed a Man-of-the-Match performance for the Welsh hosts and was a pivotal presence at the breakdown, getting his side out of a few close scrapes inside their own half on numerous occasions.
Cardiff-based Simon Thomas backed up the decision:

In the end, though, it was a try from Sam Hobbs that ensured the Italians were left to settle for just a losing bonus point, while the Blues move up to eighth.
Connacht 12-19 Glasgow Warriors
Connacht's winless streak was extended to six games as the Irish province slumped to another home loss on Saturday, this time against Glasgow Warriors.
The most troubling aspect for Connacht is that they've now scored just one try in their last three Pro12 outings, Dan Parks yet again kicking at least half of their points in the 12-19 loss to Glasgow Warriors.
It was Parks' Glasgow counterpart, Duncan Weir, who provided the foundation for the visitors maintaining their 100 percent away record this season, kicking all of his attempts for a total of 14 points on the day.
Scarlets 17-9 Ulster
Scarlets' roller-coaster start to the season maintained its course as Simon Easterby's men recovered from their disappointing 16-16 draw against Zebre, capitalising on a John Barclay try to overcome the challenge of Ulster this time around.
The Parc y Scarlets side are still yet to win back-to-back games this Pro12 campaign, but they have shown a strong resolve in their ability to regain momentum after several setbacks, a trait they'll be eager to keep.
Munster 12-6 Ospreys
In one of the most important wins they could ask for at this stage of the season, Munster managed to distance themselves from Ospreys at the head of the Pro12 table, but they were unable to prevent the Welsh visitors staying within bonus-point range.
No tries were scored in the Thomond Park encounter, but it was the superior territory gained by the home team that ensured Ian Keatley and J.J. Hanrahan saw the better of the kicking chances, outdoing Matthew Morgan's two successful attempts.
