I've seen time to time the infinite load screen ppl talk about in past but not often enough to complain about.
But lately I seem to get an infinite 'Requesting character load' message when logging off one character from a stable game sessions, to an alt. Pure random whether I will get it or not.
Fix is easy, just close eso64 client program, relaunch and I'm fine usually (sometimes get request char load infinite screen again but again same fix).
No idea if ZOS login servers are just swamped, some other resource constraint, but it seems getting worse lately.
