Block stuck at 1/783

[CyberCyclone]

I'm just wondering if there's an obvious reason as to why I can download the blockchain and when it reaches 782/783, it resets back to 1/783 and then stays there? The console logs below are all it produces. I've left it overnight several times and reset the blockchain numerous times.

I'm running Ubuntu 17.10 and Zen wallet is the latest alpha version.
