so i came across this question seeing retag and figure i create the tags. as i was about to add occultic-nine i noticed that occulticnine already existsed but must5 have been orphaned as there was no questions to it.
when i tried to create occultic-nine to match with other tages like steins-gate, chaos-head and robotics-notes which used the same naming structure as the others (Occultic;Nine, Steins;Gate, Chaos;Head, Robotics;Notes) i got this
Also i would like to know why i got this error. yes the error explains the problem however occulticnine had no questions to it (or atleast they weren't appearing when i searched the tag) so it shouldn't be giving me problems to begin with
