Research Victory by Ally, and another possible victory quirk
If one's AI ally achieves a Research Victory, is it a win for the player? Or a defeat?
If Research Victory is disabled, does the player still get the announcement that another empire has achieved the penultimate level in the Research Victory tree?
In a Suicidal game, I cannot recall if I disabled the Research Victory or not, and one just got the announcement that one of my allies reached the one-step-before-Research-Victory level. Do I need to backstab them to stave off defeat? Or will I also win if they get there?
