Here's something of a story I wanted to share with you guys.
So, as you may know, TARS is full of mature content. I had two templates that tell you if the article involves 9-11 or drugs. However, I wanted to have a template that tells people if the article has any sort of mature content. Since i'm a dumbass, I do not know how to make a new template. (I probabaly could've made a new page called Template:Mature but i'm stupid.) Anyways, I decided to rename a template called Template:! to Template:Mature and typed in some warning and put it on like 2 pages, but it didn't display right so I decided to change the 9-11 template to a mature template. I renamed the old mature template (the ! template) to Template:Determination because I'm a huge Undertale fanboy. However, when editing the Rayquaza page, the infobox was all fucked up and kept on saying Template:Determination all over the infobox. This was the same for every other infobox I checked with the exception of White Kirby's. When looking into it, I think something said something about things not showing up if they didn't have a value or some shit. I thought due to the !, that made the template invisible and prevented it from showing in the infobox. When I tried renaming it to Template:!, it said that that page existed, and when I clicked the link, it redricted me to Template:Determination, which redricted me to the current template. Once I "deleted" the page, everything looked normal again. So if any templates look weird, well this is why.
