What's Wrong?

Skills missing after the 1.2581.0 update. Code hangs or says “unknown skill” when attempting /bug, /doctor, etc. Previously created skills are no longer available.

What Should Happen?

skill should work

Error Messages/Logs

/doctor

Unknown skill: doctor

Steps to Reproduce

Run /bug and describe what happened (Skills missing after the 1.2581.0 update, and that Code hangs or says “unknown skill”).
Run /doctor first so it can collect diagnostics about your install, settings, and any loading errors. 

Neither works.
