Early TOC Position
This is very difficult to duplicate. It is really only possible to do with an addon that adds new sections to the article, and that also adds these sections to the TOC. The main body text cannot have ANY sections of its own. In this case, when forcing the TOC, or when enough values were added to trigger the TOC creation, the TOC will be the first part of the article, above any other text.
This occurs because in the case when there are no sections and a TOC is forced while TOC items were added separately, VaultWiki tries to find a valid insertion point for the TOC by searching for the first paragraph break. However, VaultWiki thinks the return value of the seeker function is a character position, when it is in fact the text of the first paragraph.
Fixed for the next build. When sections are added, it will place the TOC at the end of the main body text. In the seemingly impossible case now that it ever try to find the first paragraph as mentioned above, it will count the characters returned before attempting to place the TOC.
