Yay! Now I'm experiencing this too! I can't load onto my useless Templar Tank and now I can't even log on. I get to character selection screen, then I chose my Templar, and it won't load.
7 days for me now (EU). And I have to wait for another day, because no way you can do 2 maintenance's in 1 day, when the issue is absolutely critical! Right??...
Read this little thread. Hope it helps! <img class="emoji" src="https://forums.elderscrollsonline.com/resources/emoji/wink.png" title=";)" alt=";)" height="20" />
