Darkness and Healing...
- Added a fix for darkness while in fight with the dragon, can be switched on/off in config... (only works in version 1.13 and newer! Old versions are dark already!)
- New function and config variables for automatic healing of dragons added! Gives the dragons more power

You can change the seconds and the amount of health regained... (seconds are only 99% accurate...). 0 seconds deactivates this function (only available for V1.9+servers)
- Small fix for a Paper-NAG-Message.
- Massively improved chunk handling on 1.13.2+ servers! (Reason for this was that Paper takes a LOT more time to load chunks with each new version of minecraft. In a test version 1.12 took 20 ticks, 1.13 25 ticks, 1.14 50 ticks, 1.15 80 ticks and more, 1.16 took 300+ ticks!!!
If you have issues when starting the plugin, please let me know! I tried to test all possible situations, but i'm sure i missed or overseen some !?
