When my server host (aternos, yah I know its garbage) updated to 3.0.19, you can no longer connect worlds that were made in 3.0.18. When I asked in the forums their they said come to the mod pack providers forum. Whenever I try to connect to the world it gives a fatally missing block error. Is there anyway I can convert my .18 world to .19. My friends and I put a lot of work into this world.
