}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/offare all booleans. Quote them if you want strings.
