I was reading The Potter Family by J.K. Rowling when I believe I came across a mistake in the end. The last paragraph says that:
Fleamont and Euphemia lived long enough to see James marry a Muggle-born girl called Lily Evans, but not to meet their grandson, Harry. Dragon pox carried them off within days of each other, due to their advanced age, and James Potter then inherited Ignotus Peverell’s Invisibility Cloak.
It says that James inherited the Invisibility Cloak after he marries Lily and after Hogwarts. But doesn't that contradict the fact that the Marauders went under the cloak every full moon? Remus Lupin says in the POA:
They sneaked out of the castle every month under James’s Invisibility Cloak.
Specifically James's Invisibility Cloak.
