How do I fix this plsssss
I'm genuinely so confused, when I do 3x3 a d 4x4 I run into this problem like ¼ times. The front 2 corners are wrong and the back 2 are fine.
I use layer by later method, and I'm on the second last step where the 4 corners are meant to be in the correct spot(do not need to be colour alligned just in the right spot), and 2 are correct and 2 are wrong.
There's no tutorial that mentioned this or a guide on how to fix it. And I haven't disassembled the cube in case you were wondering.
