Ok so a couple hours ago I noticed the accounts that are bugged on my phone work on my tablet. Which is weird because, again, my other accounts work on my phone. Hopefully this gets resolved soon.
It seems that one of your account experiences this issue on a specific device (a phone), but not when you log into your tablet. This indicates to me that the issue is with your device, and missing characters/mobs/npc usually is result to a corrupt update.
However, you are stating that your other accounts do not experiencing this issue when you log into the same device (a phone) that was having the problem? I think I got that right.
Can you PM me which of your accounts works on which devices?
