Game crashes when I load a world that's in the nether

When I try to load a world that is currently in the nether the game crashes.
It crashes after it asks me if I want to backup the world and press "I know what I'm doing" it loads a bit and then just crashes.
It also happened on a (hardcore) world, which isn't in the nether but as soon as I go into it (after I closed out of the game) the game crashes, luckily when I go back into the game it doesn't spawn me in the nether, but I'm sure it'll happen again.
I don't know if this has already been noticed, but I searched a bit and didn't notice anything.
