Neil deGrasse Tyson claimed that several telescopes contributed to the dataset of orbits that lead to the conclusion of an 9th planet is impacting orbits.
He also claimed there was a misalignment of one of the telescopes and that if that data is removed there's no more mystery and everything works out.
Other theories claim that a passing star in "recent" times might have kicked things into unusual orbits and left, leading signs of it passing.
My favorite theory is a small black hole out there, in one of the papers it was in a diagram showing a 1:1 size of the event horizon.
