After updating to 2.14.0: Custom feed template breaks RSS feed

Dear support team,

I realized that my feed returns only a blank page after updating to plugin version 2.14.0. I’m using a custom feed template located in my theme folder named “feed-podcast.php”. I copied the newest template file from the plugin to my theme and no matter if I do integrate my changes or just use the original file, the feed does not load anymore. So I made my changes directly in the template files within the plugin directory, but this is of course not a safe way because it will get overwritten with the next update. Could you please inspect why having “feed-podcast.php” in the theme folder is suddenly breaking the RSS feed?

Thanks in advance,
Christian
