Where is the blockchain?
'save' command doesn't work; exit command doesn't storage the blockchain...
If you're using Windows:
It's saved in /Roaming/Tavos
Run %appdata% in Windows
Of course... it should be saved there, but it is not.
Try deleting the Tavos folder at Roaming and reopening tavosd.
If it doesn't work I'll try sorting it out, but so far, no other user has had this problem.
