I’ve found a fix for dark, broken plot worlds!
Note to staff: I was thinking about putting this in tutorials, but I wasn’t sure what area was appropriate to put it. Feel free to move it to a more appropriate area!
Go to a place it your spawn. Not on the spawnpoint but nearby, stand in the location you don’t mind a block being.
In that same spot, run /we 1
Still in the same spot, run /we 2
Run /we set 137
A command block will appear in the place!
Tap the command block.
Run /effect %p%pow 16 9999999
Job done! Remember to tell your players to click the block!
