Link2SD lost links
Just this morning when I first used my phone I noticed that all the apps linked with Link2SD are no longer available. If I click on any of the shortcuts I get an "App isn't installed" message. Almost all of user apps are linked, so I've basically got nothing on my phone but Link2SD and Superuser.
If I open Link2SD it has no apps in the "linked" section, but if I click Storage Info Link2SD still sees my sdext2 partition.
I have no idea what's going on, since I've literally done nothing to my phone of any significance in months and it was working fine. I did upgrade to Link2SD plus about a week or so ago, but that seemed to go fine. Now I do not have access to ay Link2SD plus features because the plus app was linked and is now lost.
[EDIT: I've now tried to "relink application files" from the "menu -> more" location and I get the error: "link failed I/O error"]
[EDIT AGAIN: I've rebuilt my phone from backup that is three months old and have put everything in place but any updates to Link2SD and the Link2SD plus key that I purchased. I seem to be operational. If things are status quo for a few days I'll do another backup and upgrade Link2SD to see if that is the cause of the problem)
