Research direction

Reproduce the failure with the listed Paper, WorldEdit, and CommandBook versions. Start at YAMLProcessor.java:124, then trace through DefaultsFileYAMLProcessor.java:31 and CommandBook.java:186 to determine why configuration setup receives a null file. Done means CommandBook enables without the reported exception or follow-up disable error.
