why did it get rejected if it was already approved?

So I found people who were exploiting my island by standing at the spawn without picking their spot at game start timer. This caused the game to be endless and they got to solo the opposite team without the chance of elimination. So I applied a damage volume around the spawn the would activate after the timer. I re-uploaded the map. It got approved. Then I found some people using the edges of the playing board, again causing endless gameplay. so I duplicated the damage volume around the board on the same timer. I re-uploaded and it failed the review. I didn’t add anything other than the damage volumes. Why would it fail? Today I wake up to see the live version also says failed but it is still live? 5377-1280-2071

I think the validation process is sketchy. I just got rejected after the last version passed and all I did was increase the blast radius on the explosives
