I haven't updated to the new wallet yet (too busy) but I just want to say how awesome it is that the DeepOnion team was able to release version 2.0.1 so quickly after a few users reported that 2.0.0 wasn't working properly for them. That's how good this team is.
I am still not fixed the wrong balance, I guess I better wait until the 2.0.2 comes then just install that version. However, the wallet keeps staking even with the wrong balance.
I haven't any problems with my balance but yeah, think the best way to solve it - just wait for the new version.
