Whilst it's true the park have done work to the system to make rollbacks less of a thing, they will still happen. It's just one of those things with launch coasters, even with modern ones.
Getting it back open quickly is a good sign, in theory, that they were able to pinpoint the reason why it rolled back and feel confident it wouldn't happen again.
Then again, I hear it also rolled back this morning too. Could be a weather related thing given the reasonably quick change we've had from warmer and humid weather to colder and wetter weather?
