I've been using the Semux wallet all year with no issues. I was using wallet 1.2 and today when I tried to sync it but would just stop dead at 97.77%. So I downloaded 1.3 from github, imported my wallet and let it try to sync from the beginning. Now wallet 1.3 hangs at around 94% and will not continue further.
Here's the debug.log. I edited out the ip address but the one listed was correct.
