Researching cult operations disables safehouse missions (the "small house"), not hideouts.
Oh that explains it. I didn´t realize there is a difference there. On each of these missions (safehouse or hideout) I managed to finish without ever entering the house, they always surrender before that. So I never noticed there was difference in house size. Basically it was just bad luck, that I didn´t get any bases. I was making sure everything was fine with my game.
I agree Red Dawn HQ is really hard with 8 people. But is it doable? I would say yes, as long as you have alloy vests and good men. Still, luck plays a significant role.
I am not saying it’s not doable, but currently I am stuck with armored vests (only landed UFO I got was way at the beginning, still with the basic pistols and just two agents). So if I attempt to do it with 8 guys, it will be a close thing and probably result in losses among my veterans I do not want to accept.
By coincidence I built my second base fairly close to the Red Dawn HQ, within Osprey range. So basically my plan is to wait for them to appear, load Osprey with my veterans and couple of rookies for cannon fodder and fight it out with 16 guys.
Thanks for the answers and most of all thanks for the great mod.
