I did post a solution for this a while ago, though I don't know how easy it 
is to find in the mail archives.  Anyone who can correct me on what comes 
next, please do.

It seems that, beginning with the 4.7/4.8 branch, item modifiers need to 
have an input widget in the cart, even if it is a hidden one, or they will 
be erased when the cart form is submitted.  It wasn't like this in 4.6, to 
my reckoning. I'm guessing this has something to do with the introduction 
of item options handling.

In any case, the solution is to make sure that there is a form element it 
the basket and checkout cart areas for each modifier that you use.  If the 
modifiers are display-only, in the item list, all you need is something 
like this:

<input type=hidden name="[modifier-name vpe]" value="[item-modifier vpe]">

To make the modifier persistent.  If you also want the user to be able to 
change the value of the modifier(s) in the cart or checkout item list, use 
something like the [item-accessories ...] tag.
