When placing a block anywhere in the generated world, a one will appear that lasts a few seconds, indicating that the block placed around it has interfered. This is intensified with the performance bugs that make the game much slower and without the possibility of playing, besides that, even without placing the block, the world still by itself creates random shadows where they shouldn't exist, this is a serious problem and I'm telling you to fix this, because it is not just now that the game has been showing signs that both the game's performance is defective as well as the gameplay that is rusty.
