The retreat event didn't trigger in my latest run (save file attached). By that, i mean that the "base interior breached" message and what normally follows never occurred after a long time.
The story (hopefully that'll give a clear picture of the events) :
In my previous run, i noticed enhanced bots during that event (never did in the past ~80 runs(not all got to Warlord, but still.)). Because of this, i wanted to see the events happen more clearly, so when i reached Warlord in my current run, i had that goal in mind.
After locating the Vortex lab, i decided to use my Phasing AFG to get the vortex things and delay triggering the attack and give myself more time to get back to the gate and get some defense kills. After reaching Warlord,(i was Imprinted) i opened the stash, got some stuff and went back to the gate, where things weren't going so well for the Welcome Party guards.
After trying to help them out and not doing so well(a bouncer had been reprogrammed and kept knocking me back), the guards had all been destroyed, so i retreated, and the hostiles that saw me followed me, and i ended up destroying them one by one with help from nearby derelicts.
After a few more dispatches from MC, the counterattack rang, and i helped it a bit in getting to their goal(i didn't go very far in the tunnel) before turning back to go to Warlord and await the retreat and hopefully see interactions/reactions. (At that point, i thought it would trigger once a MC bot got past the gate after the counterattack)
After a few more dispatches from MC, the retreat still hadn't been declared, and my sensor array told me there were strikers and others making decent progress through Base. Thinking it was maybe related to the Vortex Lab not being opened, i went and opened it, but still nothing.
I then began retreating and things aren't going all that well.(i don't know if the secret gate "malfunctioned" yet.)
My guesses on this are that this is related to one of the following :
-The Vortex lab not being open (an oversight, as there's no in-game logical reason for it to not trigger just because of this);
-Me not having reached the east after the counterattack(bad design/oversight, since someone would naturally be curious about the events, and them not triggering could make the player potentially lose a very good run, despite having made no mistakes there(because there's no logical reason for it to not trigger because one didn't go east));
-The event being luck-based(bad design/oversight, since one can't possibly tell the difference between leaving too early and being unlucky, meaning the player could lose a run because of this despite having made no mistakes there(no logical reason for it to be luck-based over ));
-A combination of the above.
Also, this run is a very good run, my first going above 400 hostile kills, one with 50 000 points before even reaching Warlord, one with great potential to do things to get to what i'm guessing is extended game. I know there are save backups, and am wondering if i would be justified in using one of them?
