Skills reset and console error

Deleting the skills folder doesn't reset the skills of players.

I modified the my player's .json to make all levels 0 and reloaded the plugin and the values returned to maximum levels for all skills.

Also getting this in the console:

Image failed to download! Error: Request timeout - Image Name: https://i.ibb.co/WxWf2JN/miner.png_0 - Image URL: https://i.ibb.co/WxWf2JN/miner.png
Image failed to download! Error: Request timeout - Image Name: https://i.ibb.co/xSrFSfL/alchemist.png_0 - Image URL: https://i.ibb.co/xSrFSfL/alchemist.png

first unload plugin than modify 

Changed Status from Pending to Not a Bug

Changed Fixed In to 2.0.3

Here's a copy of my config.  I'm trying to make it so that the max gather is 2x, but at level 200.  Did I do this right?
