I have stood in the middle of the 'i' and stood next to it facing it so it is in the center of my screen and get no interact options come up. I've loaded my trailer with in the end only 1 log as I quit out to read the instructions I was losing patience with getting the 'perfect' tutorial score (I know there is no scoring but getting a full tree again wasn't for my time left to play), and parked it in the black and yellow rectangle and gone to the yellow circular 'i' near the unload area to find I have no key command or mouse button to press in this area. I've played through the tutorials upto the final tutorial and along the way I found a few problems but most could be solved by quiting out and reading the keyboard/mouse commands and replaying the tutorial except one.
