I do not know what is wrong, but try use my database https://github.com/scificrypto/Federation-Credits/releases/download/v2.7.1/federationdatabase.zip
and again use --salvagewallet
That did the trick. The affected wallet shows ~ 6% less coins with your db, but I was able to transfer them without any issue. and again use --salvagewallet
Thanks a bunch!
Maybe you were mining UFC on that wallet when the fork happened?
I had a similar problem, and solved it using --salvagewallet.
Of course all coins mined after the fork are not valid on the post fork swap-chain (ufc2).
I must say, all swaps have gone smooth and exactly as planned/announced.
A big thanks to vampirus from me, even though I'm the smallest guy in every swap
