Hey, some Players on my server found a dupe bug and i also tested it on a fresh server without any plugins:
1. Find out where the world spawn is or set ist with /setworldspawn
2. Go to the end and kill the Drageon to get the egg
3. Let a second player stand at the worldspawn of the overworld
4. Place the egg at the side of the bedrock pylon of the end portal
5. The egg falls into the portal and at the world spawn the second player will collect 2 Dragon eggs.
For now i fixed it on my server just with adding a item-pickup deny flag to the worldspawn and i placed there some hoppers to collect those items
Could this be fixed?
