PhatLoots has been officially updated for 1.13+ and is 100% compatible with Quests. Kindly give it a try!

A new selection under the Edit Options -> Multiplayer menu allows you to set a level for how often you want to share quest progress between fellow party/group members using Parties and DungeonsXL. Available levels are as follows:

1. Everything (default): constantly share progress. If one player breaks a block, all players break a block.
2. Objectives: if one player completes an objective, all members advance to the next objective.
3. Stages: if one player completes a stage, all members advance to the next stage.
4. Quests: similar to previous versions' functionality. All members finish when one completes a quest.

This version's updates include:

• Only accept solid blocks for Block objectives
• Configurable progress sharing level for multiplayer quests
  
• Cleanup thunder action prompt
  
• Support new line character in stage messages
