For at least the last 70 years, physicists haven't taken the nonlocality predicted by quantum mechanics seriously enough. Even supporters of QM considered the prediction of nonlocality a liability, and tried to dismiss it as an artifact in various ways. Since much of QM couldn't be experimentally proven at the time, there was a fear that suggesting our assumptions of strict locality of action to be false would lead everyone to dismiss QM out of hand.
So, when we were finally able to empirically prove most of QM's predictions in the 80s, no one noticed that also meant nonlocality was a fact of our world, and that we should probably take the time to square that with our assumptions of spacetime geometry handed down by SR.
It now appears that to reconcile nonlocality with the things we know about spacetime geometry, we're going to have to challenge at least one other long-held assumption. One proposal suggests that not only is space nonlocal, but so is time. Another hypothesis suggests that the state of our universe at any given time is too infinitely complex to be reduced to even an infinite set of truth propositions.
