Same thing happening on my end with that piece of CC content, Alpha 189 is the first time it's ever been an issue.
Copying from a separate post in which I mentioned the issue:
As a side note (I didn't want to make this its own thread because I resolved the issue, but nevertheless think it's worth bringing up): When generating a new output on Alpha 189 and the newest Resources mod (wanted to see the new rock wall LOD), I got a notification about an unresolved form ID in cctwbsse001-puzzledungeon.esm. I went through the steps to find the errors in xEdit (there were two such errors in that plugin) and deleted the relevant properties, as both errors were for VMAD script properties. I was able to generate with no problem after doing that, but I felt I'd bring it up here since I've never gotten that warning before on past DynDOLOD versions and because that plugin is one of the AE creations/DLCs. As a test, I reinstalled the base game + AE creations and the same two form ID errors returned, which means they've probably been there all along. Just found it strange that I'm only now getting warnings about it, and I just want to make sure that it's safe to delete those properties for CC content. (Note: I am using the Unofficial CC Patch, too, and have been for a while).
