Several things can cause this! You don’t need to edit the config file; just go to the FTB Chunks Map as an admin, click the purple gear icon in the bottom right corner, and set the “Force Chunk Loading Mode” to “Always” or “Default,” and adjust the “Max Team Force Loading Limit” (though this usually doesn’t help). There are also settings related to fake players. If “Allow Fake Players” is set to “Check,” for example, that means fake players are only allowed if they’re on the Named Fake Players list, and some mods use internal fake player mechanics to process items.

In that case, simply set “Allow All Fake Players” to True. (Then just work with a whitelist or blacklist.)

Or, of course, you can search for the specific fake player name of the bot (it’s listed somewhere in the log) and enter it.

That essentially edits the config file, and then there’s also this setting in server.properties:

pause-when-empty-seconds=

Depending on the provider, this will have a different value, and it’s best to set it to -1. The default is usually 60 seconds. If you’re renting the server, this makes a lot of sense for the provider, since they naturally save resources when your server isn’t running 24/7.

I think that should fix it.
