Comment:
Yo !
It actually only failed when using the lp[x] variables instead of creating
new variables and using the to define the constraints `;-)`
Patch updated.
> Incidentally, would it be possible also to add the functionality of
deleting constraints? or should I open a different ticket for that?
It is better to create a new ticket as this one already has a patch and
fixes a nasty bug.
