Signature verification fails due to different output values

[devrandom]

I am sending dust HTLCs in a loop, and the channel force-closes sometimes due to signature mismatch.

The signed transactions differ in value to-holder by one payment worth.

• alice.txt
• bob.txt

I have logs for another one, where Alice detects the mismatch instead of Bob.
