as the subject title indicates...

I created a linkgrabber filter rule (like offline) for 'uncheckable' linkstatus, so I could quickly (on mass) recheck online status of those objects.

So once created, to reproduce

add a series of links of which some are uncheckbable in multiple packages (mine had one uncheckable object in series of packages)
auto expand them all (ctrl left click) to make visualisation easier
selection of rule in side panel
right click, check online status

you will notice all objects within the first package which contains 'uncheckable's' online check will change icon to '?' then to result... So it selecting the wrong objects for action.
