A paper fork/1.12 continuation that aims to prevent skylight lag, allow changing the server brand, and more.
If you want to patch more exploits other than these use my bukkit plugin https://github.com/moom0o/AnarchyExploitFixes

These options are in papaya.yml.

Max time for light updates, wont perform light updates if it takes too long. Patches the popular skylight lag exploit :)

Change the server brand from Papaya to whatever you want! This is shown on some clients/in the f3 menu.

Remove the console spam messages like Player_X went too fast!

Hide player ips from when players join your server.

Hide player coordinates from when players join your server.

Removes the connection messages from console for when players join your server. This will not remove the messages ingame.

Hide player commands from console. Useful to hide messages/spam

Prevent chunks from generating past the world border. Chunks generating past world border seem to cause lots of lag problems.

Allow or disallow the chunkdupe

the time in ticks the pathfinding waits until it calculates a new goal, the higher its set, the less often mobs get new pathing instructions

Prevent chunks from loading completely, great for auth/queue/limbo servers.

Set true to allow players to break indestructible blocks with exploits, recommended to leave this as false!
