Unclear "generate from png" hard-set settings?

[Jon Skocik]

Hey there, I wanted clarification on world-settings.json getting reverted back to 'factory defaults' when generating a new world utilizing the map.png method. I have been trying multiple map sizes from 1k to 4k to 8k and even 10k, yet every time the map loads in worldSizeX and worldSizeY are both factory reset to 4096. Is this a hard coded option? It appears each time the plugin attempts to load in a map.png it saves world-settings.json even if the file already exists.

I attempt to set the file to read-only (to prevent overwrite) and it would not generate the map, and subsequently crashed the server out.

Any insight on this would be terrific, thanks!
