After updating to 1.12 the server is running fine along with the plugins.

CommandNPC however is having trouble reading the commands from the previous version (1.10.2)

I tried creating a new command and it erased all of the commands on the server
commands.yml.txt
commandsold.yml.txt

I tried copying the syntax after seeing the updated syntax when the document was overwritten but it still did not work. Is there a way to do this without adding the commands one by one? Thanks!
