If you “register” (two users), then “create lobby”->“create game” (“5 in a row”), join with the second user, and click the grey area on the left hand side multiple times (somewhere around 20), you sometimes get the following mystery stacktrace (and a 404 after clicking), and F5 ‘fixes’ the issue, but after more clicking the issue will return.
