Problem 1 = The date of the revision (Dec 29, 2021) does not match the date of the stream record (03-15-2022). Is there a way to know that revision 3354837 was made months ago even though EvenStream reported it months later? I am also seeing duplicates where ES reported it correctly on the date it occurred then reports it again months later. As was the case here.

Problem 2 = The links in the diff do not fully match the links in the stream record.
