I've only come across it when I'm using mod/admin tools. It goes like this: change the password, login, new pw isn't recognised for the mod action yet I'm logged in. If I wait a long time then everything is back to normal (with a new pw). What makes it more annoying is that the "wrong password failed logins" mean that at some point I get the "too many failed logins" cooldown period, which is annoying.

In itself it's not that horrible, but the fact that it's happening seems to point at some underlying issues. And that's worrisome.
