The issue happens on /1v1 setpos

This is the error I get: :/

PHP:

[17:52:01] [Server thread/CRITICAL]: Unhandled exception executing command '1v1 setpos lol pos1' in 1v1: yaml_parse(): end of stream reached without finding document 0

Help would be great!

Okay thanks for the reply but would that not create another config or remake the current one as it says "new" just asking?

Thanks mate

I got the same confusion too when I saw the Java line `new File()` I really miss those old days.
