Missing content in new style documentation

I was reading documentation about terrain and find out some completely empty pages in new style Unity documentation, like this one about TreeInstance:

However, Google still find some pages probably in archive from old style documentation, where I found some content available, i.e. TreeInstance page in old style:
http://docs.unity3d.com/412/Documentation/ScriptReference/TreeInstance.html

The same is for TreePrototype. Not sure how many pages could be missing in that way, but could you please put back some information from these archives (at least lists of variables and functions) to make sure that content would not get lost when archives will be removed.

I also noticed there are console errors in the documentation.

It also seems most pages I click on no longer have any c# examples to look at?

Please submit a bug report and post the bug number here. Looks like some of the Tree things are missing.

Well, some years ago all the examples were written in JS and we had tools that converted the JS into c# for the docs. Around 80% of the examples converted, and 20% were missing. We’ve now started to convert all the examples to c#, and have tools to generate the JS versions. I can believe that some pages have no c#, but I’d be surprised if it was “most pages”. Do you have some pages to share?

Submitted. Bug number is 659404.

Okay, doc team have the bug.

I was going through the UnityEditor and EditorGUILayout at the time. e.g.
