Trying to restore wallet from seed on a QT wallet.
When I do this, the wallet has no Firo, no history. Looks like a new wallet.
When I replace a backed up wallet.dat file, it works.
The old wallet.dat makes the wallet look like an older version.
The wallet.dat is not related to the wallet UI. If you copied an old wallet.dat and you see an older interface, it is most likely you started an older firo-qt version.
