Disabling the timer did not help anything therefore it has been disabled and we're switching back to the old "mail to first character to login on account" , see the announcement in events.
maybe new stuff like this needs to be tested more thoroughly?
and maybe put it into a situation where it can be stress tested as well
FYI - as Saito and Iso posted on another thread, it was tested, by a lot of teamlers from all the communities. I believe some of the actual testers had a part in it as well. And, as mentioned, everything worked during those tests. When it was deployed to live servers however the hamsters got sick and took a bunch of sick time.
