Unable to Rejoin singleplayer PVE raids!!!

This isn't quite a bug report (unless your able to rejoin when playing alone.) But I hate having all my stuff revoked from me because I get low memories. All loot and stuff is taken away because I have low memory. The pain of losing all my crap because I can't rejoin PVE. Now wishing I had Tabor friends or a second headset to just sit in raid so I could rejoin.
