I've been getting this error every 2-4 hours randomly as well. Also been having the slow npc general load issues. Often missing out in fates because nothing will load in time. I have also fell through the floor and have had to teleport to get out. This game is fun and I really like it but the lack of support the bugs and technical issues that remain unattended is really pushing me to not renew my sub and just calling it quits.
