I have a template which has a number of styles based on other styles.

Now, whenever I use a document based on that template, any time I try to create ANY style in the document - even trying one based on the Normal style - I get the "The style you want to create is based on too many styles" message.

I get the message even when I try to update one of the existing styles in the document (using the "Update <existing style> to match selection" popup menu item).

Is this a known limitation? Or have I done something wrong?
