So first i tried to remove 0_0 and 0_0v a few times but each time when i jumped back to 0_0 it was the same format of the sector, a few ships, 3 secret stashes and one claimable asteroid, but no boss.
So i just tried a workaround.
I started a creative game, teleported to 0.0 jumped out of the sector and left game.
Then i copied 0_0 and 0_0v from the creative game to my "bugged" game and jumped back to 0.0
It worked the guardian spawned.
