What beginners mistake from my side. Shortcut I created was linked to old wallet version and never to version 1.2 of Ucoin so that's why I was unable to sync.
Now all going great here are two more working nodes:
165.227.151.91
45.76.16.182
Nice to see you here
majsta. I recall you were one of the main supporters back then.
So whats up? Did you decide to keep the old chain running?

I also do not see much sence in turning perfectly working coin into ETH token (while losing every unique feature UCoin had), but I hope devs have some idea on what they do and why they do what they do.
