What i did / Steps to reproduce

Swap the storage from "file" to "sql" (MariaDB driver).

Expected result

The live/players.json key in the bluemap_map_meta table to have the locations of my players.

Actual result

The field being empty.

Context

Additional information

Markers from the MapTowny plugin load up just fine, it's just that players do not show up using an external webserver.
Currently, I band-aid fix this by having /maps/world/live/players.json be proxied by the external webserver to the BlueMap internal server, however, I'd like to disable the internal webserver completely in the near-ish future.
An update that places the player locations in the database rather than relying on the internal webserver would be desired.

In your plugin.conf is the write-players-interval set to anything or is it commented out?
If that is not set to anything (default) then this is expected behavior :)

This key did not exist for me (apparently, my config files were outdated - which also explains why it only used 1 render thread instead of 3).

After updating my configs and setting the write-players-interval to 5 it now functions as intended.

Thanks!
