Hate to say it but I disabled SHA again.
I tried loading the wallet on another box that is perfectly sync'd and the transactions that had confirmed on the exchange are not confirmed at all in the windows wallet.
We need to hear from the developer, this is way to wonky to continue to send coins etc, no matter what chain we are on. How do we know the block explorer is even on the right chain? ;-/
i think one or more nodes you added is bad node. and you will see that after u keep only 3 nodes.
maybe you need download the chain again on the exchange with the dev's nodes only.
there maybe only 1 chain but some nodes have problems dealing with.
