Currently, if a page name consists of a colon, any includes or excerpt includes are broken because the format now for including an include or excerpt include macro is to input the space key, colon, page name.
If a page name has a colon in it, the include errors.

Either need to escape the colon in the page name so that the include doesn't break, or have the actual db reference be the tiny link to normalize the info and not be affected by a change in the page's name.

Note: With the recent release of the feature to allow excerpt includes across spaces (which is great!), those that reference a page that has a colon in a name break. Since there isn't a tool for us to see all of the excerpt includes, I'm not certain all that has broken.
