changing rates of moving lumber across screen

-this somewhat helped the bug, the lumber does not get stuck at the
screen as much

-the bug i am trying to fix is, sometimes the lumber that flies across
the screen gets stuck halfway through the tween and then doesn't move.
Also sometimes when the tree gets deleted it still calls the
makelumbersprite function. So what you end up having is lumber that
spawns non stop even though the tree is deleted

-you can see the bug when you go in and out of the areas, so just start
chopping then stop chopping, then sit it in till the lumber runs out.
Then the bug should appear
