I have set my anchormin and max several times now but as soon as i ext the server (client disconnects) and come back they are the defaults values

Did you reload the plugin after making the changes? Did you make sure to follow the same format, no extra spaces, etc?

In this case I set the values, did a save command; then later I had to exit the server and rejoin and my values were default again

I did not reload the plugin.

Y just tested those steps again and it did not do it (values were correct)..... not sure what happened.... totally confused.

I'll take a look when I get home to see why this might happen

I forgot to save the config after the values were set. Fixed in next update 4.8.4
