On the avatar editor, if you want to use the grid, you can’t use the button to place blocks (1) instead you have to use the button to paint blocks (3), even worse, the block will be placed 2 blocks above the grid indicator.
One other obnoxious thing when using the grid is the “search bar” on it, even if you don’t type anything in it, it will be selected if you click on the up or down arrows of the grid value, and it is really annoying, because lets say I want the grid on 10, then I try to press (3) to place the block, but it will instead increase the value of the grid to 100 because the “search bar” is still selected.
