During your ride on JL, was the audio with the Joker working? While he was moving (very slowly) he wasn't "saying" anything.
Yes, the Joker's audio was working. And just to be sure I remembered correctly, I asked my kids the same question, and they also said his audio was working. Actually, everything worked. Even the fire effect, which doesn't work about 1/3 of the time in my experience.
Yep, the fire effect was working for a change.
Not sure if there is a specific issue with the fire on the past days it has not been working, but usually just inform the operator that the flame was not working and they can reset it. Sometimes they just don't notice it is not firing and needs to be reset.
