Changelog:

This hotfix contains an important performance increase to avoid delays when joining players.

A hotfix is a small but important change, but what do I need to keep in mind when updating?
This update is very easy to install because only the .jar file has to be replaced.

Here are some update instructions:
1. Stop your server
2. Replace the old .jar file from ATR with the new one.
Note: No changes to the configuration are necessary (if version 1.8.0 was installed before, otherwise the other patch notes have to be observed).
3. Start your server

Now you have installed the hotfix and will have fewer problems if a player joint your server.

At this point I would like to thank everyone who gave me a constructive feedback to this problem.

In this sense we will see ourselves soon in the version 2.0 again, with many new functions and possibilities.....
