We kinda had a debate about that a few months ago. It was stated that there was crazy weather that lasted 4 months and stopped 1 month before the story of AO, which is supposed to be the same event when Durza exploded after his fight with PK.
Its somewhat inconsistent, since Durza’s defeat is supposed to be only 1 month prior to AO, I asked this to Vetex once and uhhh, his response was like “Dont overthink it” basically.
