I killed myself in the Sandy Scandal quest and cant get back

While doing the Quest A Sandy Scandal I got teleported into a cutscene after going into the Scroll shop after it was done i tried to look for the place i had to go to but I couldnt find it so i typed /kill to persue other quests but when I tried to go back to the scroll shop to continue looking for the Explosion I couldnt get back to the quest part of the map (the one thounsands of blocks outside from the original map) and now im here I have tried to retrace my steps to get back and I also tried doing it on other servers but I just couldnt get back and that leads me to this thread to find a way back
