I've just noticed wrong conversion in the "preview" of periodical ebooks (see attached image). This only happens in such preview (don't know the name, but is the default when you open a new periodical ebook and in the Kindle Touch is symbolized by a 2x2 grid icon).
As the article text is fine this is almost a non-issue, but maybe you want to have a look for the shake of perfection.
Yep, is hot here
