I'm coming towards the end of a mighty tome (454,000 words as of today). Due to its complexity I decided at an early stage to divide the books into sections that are separate Word documents.
These sections all use the same stylesheet, where 'Normal' is the default style (first line indented) with '1st Para' having no indent.

However, one of the Sections has, for some reason, changed all the styles for '1st Para' to 'Normal'. Now, after changing a few back to 1st Para, they all seem to have followed suit.
Thankfully, it is only the one Section that's affected, but has anyone else encountered this before?
