14 and 16 were the part IDs

We're on 2.7.0.

It's one of these things that's happening just often enough that I'm
leery and would dearly love to know a mechanism by which this can
happen.

What has to happen on the network for this to happen? Essentially, it
seems like they are getting their original page reloaded. This could
also explain the case where a student was unable to change a trailing
answer in a problem (though this was supposedly replicated in front of
Chuck and an instructor).

How does LON-CAPA keep a browser from caching a page, and are there
situations in which a browser will cache it anyway?

Later,
Mark
