help missing something

My first guess is that what you are really missing are the two trees that are included in the Support Files download. Make sure you download and install them. Failing that, you need to be much more specific than "the hollow tree stump."

The one for Fargoth's quest? I think that it might not have survived the conversion. Previously Eloth pointed out that containers which had no weight (like the mummies) did not convert unless morrowind was modded to give them weight. I think that the hollow tree stump could be a similar case. However ... Fargoth's quest has not been remade ... so you probably won't find anything in it if it was there.
