Unable to connect to server

[Anna Bakker]

Sometimes all players online lose connection and the server shows that all those players and the server are still online. Both with !list and in minecraft multiplayer menus.

Each time I have seen this happen I've needed to kill the server and restart it. And this is starting to happen more often.

I also believe that most of the times this has happened the last thing I saw being used ingame on the server screen was commands from /greturn, specifically /god off.

Server screen when this happens:

I don't see how this can have anything to do with scripts?

[Anna Bakker]

Wasn't quite sure where to put the issue

[Riot]

There's simply no point putting it here, since nothing we change in scripts can fix it; it may be an issue in Canary, in which case it needs to be diagnosed that way, or it may be an issue with a plugin (such as whatever currently provides /god functionality) - in which case it needs to be reproduced and then reported to the appropriate repo.

Either way it's not helpful to have it here, and the issues for scripts are already cluttered enough - reopen this if there's any indication that it's a configuration issue or something else affected by something in this repository.
