When opening and closing chests/crafting menus/other menus quickly while moving the cursor in a direction, the cursor seems to get stuck and moves in a single direction. This can sometimes be corrected by opening and closing menus quickly and moving the cursor in the opposite direction but normally just makes the cursor move erratically.
This does not affect the movement of the character in any way, but when the menu is opened back up, it continues to move in the same direction. It seems to be a bug in how the menu interprets where the cursor is supposed to be rather than the analog stick/directional pad actually being stuck.
