I have a very strange issue. When using the Visual Editor to edit one specific template on my wiki, after making edits and hitting "Apply Changes" the editor just loads forever, never saving. It seems to only happen with this template: https://obeymewiki.com/wiki/Template:Card
This is also a new issue, having only started a few days ago despite the template being used frequently for a long time now. Other templates used on the same page as this template also have no issues and work the same as always. Using the Source editor to edit this template also has no issues.
