Now, Northampton prop Tonga'uiha has thrown the cat amongst the pigeons by signing a new deal with the Saints - three months after he agreed a contract with Saracens for next season.
As a result, everything is kicking off.
Edward Griffiths, Sarries' Chief Executive, isn't exactly full of the joys of spring. In fact, he has slammed Northampton and called them "April Fools".
He said: "On April Fool's Day, Northampton have announced they have signed a new contract with Soane. This contract is illegal and irrelevant.
"The sad reality is that a proud Premiership club has brought our game into disrepute.
"They have shown complete contempt for legality, justice and integrity and have made themselves look like the ultimate April fools. We must now decide whether we operate a league where signed agreements mean something and are respected, or whether we have chaos."
So he's not a happy Easter bunny then.
But what's going to happen if Griffiths gets his way?
If Tonga'uiha's Saracens' contract stands up, are they going to force him to join them? Do Sarries really think they're going to get the best out of a player who would rather be plying his trade 50 miles up the M1?
Time to wheel in lawyers, but it would be nice if this could all be sorted out sensibly and behind closed doors.
