Yes and yes. Try potentially permanent lung damage and toxic material concerns. "Mess" doesn't begin to describe the fiasco that has been constructing Shanghai Disneyland.
As for Tokyo Disneyland... I won't pretend to know more than Spirit, but plans are certainly being scaled back. There have been problems with securing cheap construction labor in Tokyo in light of the upcoming Olympics there in 2020. Any remaining construction crews come at a heavy price, so major cuts will be/have been taking place to the work at Tokyo Disneyland (and even WDI staff).
No, everything in Shanghai is MAGICal. I know this because Burbank tells me so.
As for TDR's massive plans, if you want to compare notes feel free to drop me one. But I have heard nothing at all to suggest a scaling back. I know people have been pulled from work on it due to SDL's continued issues, but that has also delayed Star Wars back here, yet no one will ever say so. ... I would be shocked if anything other than delays are going on at TDR. The OLC has needed and wanted an aggressive expansion plan and this is it. ... As for labor, there is plenty to go around. This is Tokyo in the 21st century.
