@neil I don’t think this should be happening:
See the “tags changed: votes-friendly --> votes-friendly”
This change is noted on every page of the post’s history.
It also seems like when a new tag is added we say “tagX --> taxX” instead of saying “tagX was added”.
I think this is related
As if the last tag change or maybe the first (who knows) is persisting across all entries, it seems to me that would explain why the post edit history doesn’t show all of the tag changes that have occurred on said topic.
Did we resolve this @neil?
I just pushed a fix for this one. The data is correct, but the UI was displaying it wrong.
