Bek yeah, you trashed it pretty good - nice find! ?
Steps (bulleted points helped me understand better)
- Create tag X
- Create tag Y
- Drag tag Y so it is a sub-tag of X
- Delete tag X
- Both tags are removed, refreshing loads error screen
Bek I didn't see any relevant issues
Can you create a issue? If not I will create one later
