A RuntimeException happened while ticking the server about powernukkitx

Before I can solve your problem, I'm going to need a little more information about the problem you're mentioning.

1. Have you added acustom mapor a server-generated map by default ?
2. I can see, there's a timeout from connecting to the server, which could be due to a number of things The connection to the server is too long/If the timeout is direct, it could be due to the server installation.

😓 Sorry for the late reply, but if the problem persists you can always try reinstalling the server, as I've never had this error. It could also be due to a plugin.

I got some other people encountering the error and the source is mostly modification of region files during server runtime, because chunks, loaded in NukkitX, cannot be found after their properties have changed.
Like AzaleeX pointed out, in some cases you imported a world with corrupted chunks, which also could lead to the error, but I didn't investigate that one further.

I have the same error. I try to fix it that way:
cf87bb3
But I did not test it yet because PNX is currently broken for WaterdogPE. Waiting for my PR.

I have to mention that the map I am using was NOT imported. It was server generated.
The server was running for a while. It seems that at some point, unloadQueue.size(); and unloadQueue.fastEntrySet().iterator(); are out of sync. But I cannot explain why this is happening..

This error is pretty critical, since it prevents players from joining when the max player count is set to 1. Players will get a "Server is full" message even though the server is empty.

I haven't added custom map; my world was generated by PNX by default.

Regarding the issue of player timeout, we can rule it out since the player exited normally at 08:27:40, while the runtime error occurred at 08:36:14.

In my case, this happens about 10 minutes after all players have offline.

You've given me some food for thought, perhaps this is a block uninstallation issue?

I'm going to investigate further and try to reproduce the issue after setting the max player count to 1.
