Make a Service article errors

Paragraph 1 - my rant:

One of the biggest frustrations that I’ve found since beginning to use UE4 (as a student who has no prior knowledge of programming, level design or the Unreal Editor) is that each incremental update to UE4 seems to change node names and locations in the blueprint editor. Not a huge deal, but then the UE4 documentation isn’t updated to reflect that, which stalls everything that I’m attempting to accomplish as a novice who desperately needs these support articles to do so. It seems that you get some hand holding in the beginning of these support articles, but as you progress, it seems that it must’ve been nearing 5pm on a Friday evening and the writer had plans, so he just threw up a picture and said “copy this” rather than giving more thorough explanations like what was done earlier in the article.

Paragraph 2 - the issue:

Currently, in the “AI & Behavior Trees” section of the UE4 Documentation, I have worked my way down to the “Make a Service” section. In step 5, the reader is told to “create the following graph”. There is a link if you want to just look at the picture and do it manually, but there is also the option to copy and paste the graph data into your own blueprint, which is what I chose since I am a novice and currently short on time.
As per the usual, a whole bunch of node names have been changed or moved around since this document was written, so after I pasted the node tree, the whole graph became ripe with errors saying that nodes cannot be found and what have you, thus stalling my assignment.

I don’t mind the updates, but it’s going to be quite a while before I get the whole “visual programming” thing down to where I know what’s what, so I would greatly appreciate two things:

  1. How do I fix this so that I can finish my assignment
  2. Please update articles when UE4 gets an update to reflect the changes, or just give me a link that I can bookmark, if one exists, that states the specific changes, like “AI_Con_Ref has been replaced with [insert node name here]”

Thank you for your understanding and support!
