My thralls (and buildings) have also vanished #1953PvE. I have been consistently logging on at least weekly for about 9 months as I had an detailed and complex build. While it might be possible I missed a weekly log-in (thus building loss), I find it very hard to believe I did not log in for ten days and so lost all my thralls. I have also found that global chat isn’t working on that server (Ctrl T).
