Ok, I have a parent category "Star Wars". It has 15 sub-category's and I'm having trouble adding another one. I'm trying to add the sub-category "TAC Collector Coins" to the parent category Star Wars.
Now, at first, I though it was just a glitch, but I added the sub-category to the parent category "Indiana Jones" and it added it straight away. Obviously, this is a Star Wars item so can't go in another other parent category, it needs to go in the Star Wars parent category.
I've been trying for like 18 hours to add this sub-category, so why isn't it adding? Is there a limit on how many sub-category's you can have per parent category?
