hmm binaries are at 120044.. should be 120045?
Exactly HOW did you delete which wallet.dat (a normal one or one in the "backups" folder) ? Was the wallet/daemon still running?
Which name did you give the new wallet file?
Which operating system?
v0.12.0.45 looking very good! updated two nodes and appears to be stable w/ low CPU usage (~5%) after reindexing / sync
