I think the compass at the top of the screen is slightly offset. I have some screenshots to demonstrate my point:
My tests were done by walking into a flat wall of igneous stone.
I start with my compass facing directly east by lining up the grey arrow on top as central as possible to the ‘E’. Then I walk forwards into the wall. I end up going off to the left.
(Picture 1: standing still, lined up to east. Picture 2: after a couple seconds of walking forwards.)
What demonstrates my point even clearer are these next 2 screenshots. I do the same test as before but I am pointing slightly to the right of the ‘E’ and I am still moving off to the left (albeit very slowly, but still left)
The last screenshot here is me walking into a flat wall after I have found the central point where I do not move left or right. So this should be true east. (I got rid of the stone block to the right of me to illustrate that I’m not being anchored by anything).
Is this a big issue? Hell no.
Does it bother me? Hell no.
Is it wrong? Hello
