[D&D 5e] NPC Traits Not Showing in Purchased Modules

Since the latest lighting update, my friend and I have been having difficulty with NPC traits not displaying correctly on their character sheets. The names of the traits still appear but their details are absent. Clicking on the trait to make it appear in the chat also displays none of the traits details. Approximately half of NPCs are affected by this problem, the other half are working as normal. We have tested this separately for CoS and ToA on different PCs and in different web browsers but the problem persists. Is anyone else having this problem?   

I'm the friend, can confirm that I'm having the same problem as of today.

I am also having the same problem.  I noticed it started this morning 4/15/20. In the Storm Kings Thunder module some of the monsters have traits missing like the Piercer, but others like the Remorhaz seem to be ok.

Confirmed here, too. This might be related to the recent change in the Repeating Traits attribute name from "desc" to "description". Yes, the trait is visible if the keyword is the old one: "desc". I suspect a dev needs to run some sort of conversion or update. EDIT: I have reported this.

Thanks for the report. There was an issue with some of the NPCs in Marketplace items. Those sheets were not triggering an update to the sheet, but now we've pushed code to resolve that issue. When you open those NPC sheets, the update should take place without any action on your part.

Thanks Kenton! Once again, the world is safe for monsters. :)
