Playing around in a new campaign, and trying to add Alert via the feat tab on the sheet, but whenever I do it immediately crashes the entire sheet.

It's an additional origin feats, but any reason why? Because adding other origin feats this way causes no problem.

Please fix this, apparently, easy bug.

I have been able to add both 2014 and 2024 versions of the Alert feat to my characters without issue. I have tested in Opera GX, Firefox, Edge and Chrome browsers, and both website and via app. All works perfectly.

This does not seem to be a D&D Beyond issue. Are you certain you're adding the official version and not somebody's homebrew copy? Are you using any extensions like Beyond20? Are you using VPNs? What Browser are you using? What device? Website or app? Is it only for one character or any? Are there any errors being displayed - you say it crashes the sheet, but can you detail what you mean by that, preferably with a screenshot (click here for info on how)?

It just seems to be the one character. 

Even if I try to add it via level up, it'll immediately crash the tab. Even with a copy of the character it crashes - very odd.

I'll be submitting a ticket, thanks Spam.

Turns out the feat has been added, but isn't visible, so it's basically a hidden feat.
