managing to get manual vote to work on firefox, worked at 100% votes anyway but autovoting never worked, then got some clue that the 'maintain voting %' field in advanced filter has a minimum value of 20, anything lower than that will result in some blank field and thought it might be the cause of autovoting never actually working, but now I can't test that theory using 20 as minimum because the 100% votes drained me below 20, lol...

I really like the tool and interface for it, will be a shame if there's no way to actually use it
