Right, that's the problem with Embed and, to a lesser degree, Options as well: from the wiki software's point of view, they include all child pages fully and then do more expensive computations involving the entire text. Unfortunately, wikis don't like many of those happening on the same page, so there are internal thresholds of how much a single page can do—and if they try to embed many other pages, one of those thresholds is hit: in our case, "post-include template size" is exceeded.

After that point, the wiki software shuts down any further template operations and just displays a link to the template it's refusing to work with, which is exactly why the page you mention seems to stop working for no apparent reason.

There's no solution as of now, I'm afraid :( using Embed only a few times per page should be safe, and Options should be safe up to around 30 (it also depends on the actions that are included,somewhat)

More on this when I'm home, doing any actual work on the phone is not something I'm capable of yet :-)
