Can't use yml with only Comments

[qsef1256]

Description:

1. If there is a yaml file with only comments, skript-yaml removes comments.
2. If there is a space next to the comment mark #, skript-yaml throws the error below.

It's not a duplicate of #29.

Code:

options:
	file: "plugins/Skript/scripts/test.yml"

command /comment [<text>]:
	trigger:
		load yaml {@file} as {@file}
		set yaml value "data" from {@file} to "test"
		save yaml {@file}

test.yml

# the comment

[19:39:37] [Server thread/ERROR]: #!#! If the error doesn't disappear even after disabling all listed plugins, it is probably Skript issue.

hmmmm i'll have to work out a better system for comments, perhaps a good chance to add subnode comments as well :D
