Our true aim point appears to be the exact center of the screen (which is typical), but the in-game crosshair is positioned several pixels too high.
Thank you for taking the time to report this. We are forwarding this to the team for their review.
that is actually a result of the blocks size not being the same as it's graphic.
edit - bedrock, 2nd wave holo blocks, corrosive cubes, and plasma sentinels all have a slightly smaller hitbox than their graphic indicates.
upon further testing i was incorrect.
