Help find the error. (Diablo 2)

Greetings. I haven’t played in d2 for 7 years and I don’t see something in my opinion. Now I have level 43, the number of distributed skills is 48, I play on a nightmare, I completed 1 task of Act 2. Accordingly, I should have 49 points, not 48 (43 for levels, 4 for tasks on the normal, 2 for a nightmare). I decided to drive it up to the radio moment on the normal, for some reason it seemed to me that I had not taken the book from him. Whatever it was, she did not fall again. 1 skill lost forever?
And the question is in the appendix. Where can I get a drop list in the form of a table? A couple of days ago I was looking for an hour - I did not find it. This table contained everything: from whom it falls,% of the drop, the image of the thing, characteristics. A very handy thing. Help me please.
