They're not going to give that info out (plopped on bedrock) unless it is disinfo, meant to make you expect the thing to go. Foreigners did most of the engineering. The warping was a misinterpretation (or more disinfo) of a satellite photo where heat rising from the dam distorted the air. Rumour is that bad actors among the foreign engineers placed bombs before laying the concrete, so if true that would suggest they are being held hostage. Kill off your population with 5G and covid, or else. It would be good to see actual data on the build.
