However, Kiske started suffering health issues related to his voice shortly before starting the tour, to the point where after the first two shows in Mexico, his involvement for the next dates was unsure. He was cleared to perform by doctors in time for the next show in San José, Costa Rica on 23 October, although his illness forced the band to temporally remove a few songs from their setlist, and to have Deris, Hansen and Gerstner support him more vocally. After accusations from fans of Kiske using lip sync on the more vocally demanding parts of some songs, Kai Hansen confirmed that Kiske had indeed partially used taped vocals, but only for the tour's opening show in Monterrey, and because the band feared they would have to cancel the show, as Kiske felt unsure he would be able to perform at all due to his illness. Kiske stated in 2021 that "it was the hardest tour that I ever did because I caught a freakin’ virus somewhere in South America and I couldn’t get rid of it. Like, after four weeks, like the middle of the tour, I was only able with huge glasses of red wine and painkillers to go on stage because my immune system was going nuts." With regards to the taped vocals Kiske explained in a 2021 interview "I never did anything like that, and I will never do that again…When you do a playback, you've gotta be doing the same thing as on the recording, and I was, like, holding the microphone to the audience and my voice was coming through the P.A. and stuff like that…I didn't have a choice. The other choice was to cancel the show, and the band didn't wanna cancel the show." On 28–29 October 2017, the band recorded their concerts in São Paulo, Brazil for a future live album and DVD.
