Yes, blockchain has been stuck at 750 for several hours now. The dev is probably sleeping now, hopefully he tends to this issue when he wakes up. I do like how this coin had a fair launch with no premine despite these issues.
Was going to get up a block explorer and additional node, but the linux wallet won't start.
I will try to compile the linux wallet and test it. Does it give you an error or does it simply not start at all?
