I have an older minecraft world in which i wanted to load a new end dimension in so i deleted the DIM1 file and when I go to the end the towers are in the circle but no Ender Dragon or portal in the middle
What I expected to happen was...:
End island correctly spawns in with portal in the middle and Ender Dragon ready to kill me
What actually happened was...:
End island spawns correctly with no dragon or portal in the middle
Steps to Reproduce:
1. Have a previous version of a world
2. Have a generated end biome
3. Delete DIM1
4. Go back to portal to enter dimension
As I recall, you need to edit level.dat (using NBTExplorer or a similar tool) in order to reset all information about the Dragon fight (/Data/DimensionData/1/DragonFight/*) - if you fail to do so, it will remember that you already fought the Dragon and will not spawn a new one.
