I haven't really done much configuration in the past for major plugins, so when adding loot for each category (easy/med/hard), my console spits out issues about unexpected characters when parsing the config file, I assume it's my lack of skill and knowhow on doing some of this stuff, and am not sure how to go about fixing this. I'll add my config file if requested, but here are some error codes from console:

[Raidable Bases] After parsing a value an unexpected character was encountered: ". Path '['Loot (Medium Difficulty)']', line 1332, position 4.
[Raidable Bases] Invalid character after parsing property name. Expected ':' but got: (. Path 'Treasure', line 1198, position 9.

yep, that's a json formatting error. jsonlint is also another good site

it does tell you where the issue is. so go in the file to the line and fix it by doing what it says

Using a good text editor such as Sublime Text Editor, it highlights formatting errors.
