Trying to build a ramp from a cliff down to the ground, starting from top and working my way down, I can get all the way to the bottom and finish the ramp but if i log out then in, or leave the area then come back the bottom half of the ramp (wooden small stairs) have vanished, not invisible, just gone.
Similar issue when building a ramp from the top of a redwood tree platform using stone stairs i can get half way to the ground then I can not place anymore stairs, Tried building off of a different side thinking something on the ground was obstructing the stairs, tried wood and metal stairs, small step and regular steps and the same thing happens with them all> i get halfway down then cant place any more, if i move around and re position the stair until it shows green and place it the entire staircase gets destroyed as if the top most stair was demolished
