I did a check of the fake 137571 block, and the
only transaction that's there, but not in the real 137571-137573 blocks is the generation one. Which is what you'd expect from a "legit" dupe block. Looking through the other one now.
edit: Same with the 136755 block. Only generation block is missing.
I'm seeing the same you are. We'll have to check the other blocks too, I guess.
Unless ABE is hiding the conflicting transactions that should have been included in those blocks?
