Hello ~
After the new touch control modes update, I always used the joystick with crosshair mode. Which is perfect for a player like me who uses 4 fingers to comfortably play the game. Now, after a couple of sessions, I noticed that sometimes when I hold 2 fingers together (like holding the attack/place button while moving the camera) the camera yanks to any direction. This was getting annoying while building houses, and I noticed that the attack/place buttons also move the camera around. (You can check this yourself if you want)
It seems that if you hold/press 2 fingers and move them at the same time, the game doesn’t know what finger should it follow. And after you release one finger, the view/screen yanks to any direction.
