Under the stable Ito release. I went to the bottom of the Amigara mine. Hacked the computer and did the tremor test. Then ran back to the surface. After a while I went back down to see what was up and saw some amigara horror corpses at the bottom of sinkhole pits on the level above the bottom level of the mine. As well as a random artifact. Dunno if things are meant to work this way.
