There was one the day before you made this post. DTTG 3 is corrupting files - #270 by OogieM - DEVONthink To Go - DEVONtechnologies Community
More properly, workarounds, as the cause is still unknown.
Finally, the problem I reported with duplicates involved files that had different links with the same display text.
So files that differed like this:
[bookends](bookends://sonnysoftware.com/77131)
and
[bookends](https://www.amazon.com/dp/B08PTWF1DF)
would be treated as duplicates.
If I, for instance, saw those two files listed as duplicates, I might delete one or the other thinking they are actually duplicates, when in fact one was correct and the other not.
I’m surprised the majority of users would want this behavior.
