Talk:Quest List Template Broken?

I've noticed the template Quest List template (https://ddowiki.com/page/Template:Quest_list) throws an error when used on other pages. The error says "Expression error: Unexpected < operator." This error can be viewed on pages such as Keep on the Borderlands that call the template. &rArr; Laviathen of Cannith (Contribs • Message • Email ) 11:50, October 3, 2021 (EDT)
 * Urgh. Looks like some sort of typo within the (hideously badly formatted) template itself. I'll have a look and see if I can spot what's gone wrong, but don't count on it. &rArr; PurpleSerpent (Contribs • Message • Email ) 13:35, October 3, 2021 (EDT)
 * There's nothing wrong with the template currently. The problem is the template calls are missing 'quests' as part of the category name per .  &#x1f45f;&thinsp;ShoeMaker (Special:Contributions/Technical_13&thinsp;•&thinsp;User_talk:Technical_13&thinsp;•&thinsp;Special:EmailUser/Technical_13 )&thinsp;&#x1f45f; 00:37, October 5, 2021 (EDT)
 * Gotcha. In future, though, it would have been a good idea to put some sort of note on the template page, or even the talk page, because without that information I doubt any of us would have been able to distinguish between "broken" and "working, but looking for a keyword it didn't need previously." &rArr; PurpleSerpent (Contribs • Message • Email ) 04:47, October 5, 2021 (EDT)
