I've anonymized this log output -- let me know if you need the un-anonymized output, or if you need to see the entire logfile rather than the output from the troubled period. I'd want a confidential way of getting that to you.
https://pastebin.com/AEtpcSHMThe transaction had 3 Segwit inputs, and one Segwit output (change) and one legacy address output.
Ignore the errors at the top -- I had an issue with the flashdrive, after I realized this and used a different drive I was able to save/sign/broadcast the transaction normally. I was never able to make RBF work -- no errors or crashes, Armory just didn't do anything when I clicked on "Bump fee" on the context menu.
