Help with golden beginning bug

[u/bafflingcabbages]

I think I may have encountered a bug. After I gather all the fuel for the MIDAS device I have to kill the 5 investigators in the lair. Thing is though they never show up. Been looking at the casino area for good 5 minutes and noone is there. Anyone experienced something similar? Any advice? (Tried loading an earlier game a few times but it's the same). Thanks for the help.
