At least we can all agree on how bad the tutorial is... :D
We've had a few run into the issues (myself included) but it hasn't created a stop for us yet. Those guilds close on certain phases/stars for that phase will likely feel upset as they're being shorted out of rewards others are likely to receive. Obviously if rewards are distributed this would make the top guild come out on top and the medium strength guilds trying to catch up set back even further than intended... If a mass reward is distributed this is even more problematic, as those shorted by the bug won't really be compensated.
And I agree nobody was pushing for TB to be released in August. Many were speculating September early and December at the latest (and of course that's just speculation), so late August was nothing but a surprise. But the point here is the devs chose to announce the release, and release particularly sub-par content. The only "active" part of the content where you use the actions and abilities of your characters will sometimes give a player 0 credit when they deserve full credit. I would classify that as a pretty major bug...
