Thanks for the replays, everyone!
The no effects bug was fixed by updating to a new version, but that means that for all matches I watch that were played on that version, I don't have effects. Too bad so sad, I don't think there are any matches from that version left that I really wanted to cast but it did make some a lot more difficult/less fun to cast. It was also very annoying the few times I played during the update but oh well.
