I've got this error (compiling from source, Ubuntu 14.04)
The wallet otherwise works well. I'll see if it can automatically transfer 25% to Poloniex or if I have these S4C issues again.
Also: deleting addresses on the addressbook still doesn't work. I know you are aware of it, so just mentionning.
A feature request: render "custom change address" inactive when "return change" is checked. I know that you might want to exceptionally use a custom change address and so it would override the "return change" but this might cause more confusion than the flexibility allows.
I think there is a CSS3
:window-inactive, as well
:disabled pseudo-class, might help.
Also, it seems there is a major bug here
http://imgur.com/a/67gK3#0The age issue was fixed with repairing the wallet, but not the rest.
I reopened the wallet with 1.0.6 and everything went fine, I could reorder the block as expected. When I reopened the wallet in 1.0.7, the reordered block were still reordered but the warning about the errors in wallet.dat still resurfaced. It seems I will have to use 1.0.6 to use control until this get fixed. My next move will be to test S4C with 1.0.7. If it doesn't work, I will consider opening two sessions of HyperStake (with different ports) and slowly moving my coins to another wallet (it could take two weeks to happen).
Interesting I will look into these issues. I did change how the fee is calculated from coin control, and from my experience it was more accurate rather than less. I'll do some more testing with this and see what I can do. As for age.. that is very strange.
Edit actually after looking at age, I would guess it is because the transaction never confirmed to the chain, and the age is based off of blockchain age.
I'm actually fully in profit now, but that's because I was in from the beginning and had to sell a bunch. I'd be happier had I been able to keep it. It is one of the best for staking.
