renshuu seems to be awfully lagging today. First I get this "can't connect to website" screen, then, new quiz question and the dictionary take an eternity to load.
don't know if it's related, but I also can't upload mnemonics because the pop-up box is not scrollable no matter how many times I reload the page and retry.
i even had an instance where I tried to look up a kanji, but clicking the desired kanji redirected me to the latest quiz end page.
