Common Minecraft YAML Issues

Tabs vs spaces: YAML forbids tabs for indentation. Plugin configs often break when editors auto-insert tabs. Use 2 spaces consistently.
Special characters: # starts a comment (unless inside quotes). & for color codes should be quoted: name: "&6Gold".
Lists: start with -, indented further than the parent key. Inconsistent indent on list items is a common bug.
Nested keys: indent deeper under the parent. Don't mix 2-space and 4-space nesting in the same file.
Booleans: true/false/yes/no/on/off are all booleans. Quote them if you want strings.
