Are there any situations in which 2xSV does not generate singularity? I was playing against a rainbow in plat just now, and it played 3 SN in one turn without getting any singularities. I was watching carefully: it certainly did not generate sings the get rid of them with pc. They never appeared.
There were no particularly odd circumstances. It had F bonds and hourglasses for permanents, werewolves in the field and a titan weapon out. I was Sosacced at the time. Could this affect it?
