skill tree stops working when edited

I tried multiple times to load the plugin, edit it and o.reload it, but when I got frustrated enough i unload it, readded it, and it worked, but whenever I edit ANYTHING in the config and plugin sections, it stops working and says in console:

"Previous version of plugin failed to load: SkillTree"

and: 

"Unable to load SkillTree. Literal of type double cannot be implicitly converted to type 'float'; use an 'F' suffix to create a literal of this type | Line: 97, Pos: 50"

the line and pos stay the same no matter what i change in the code

Can you demonstrate what you are trying to edit?

can I add similar issues ? 

| [SkillTree] Error (Object reference not set to an instance of an object)

at void Oxide.Plugins.SkillTree.SendSkillTreeMenu(BasePlayer player, string tree, string selected_node) in /home/container/carbon/plugins/SkillTree.cs:line 8262

at void Oxide.Plugins.SkillTree.NavigateToTree(Arg arg) in /home/container/carbon/plugins/SkillTree.cs:line 9300

I was able to switch between skills, but after edit and reload, it just freeze and give reports

I really can't help anyone if I don't know what changes you have made to the config.
