Can't Seem To Send Out Explorers

Maybe i'm doing something wrong but i haven't been able to send out explorers on a mission for the past month or so. I keep getting an error that there was no JSON response from the backend. Anyone else getting the same error?

In the meantime, i guess the only thing left to do is to improve the skills and buildings. Maybe upgrading the ship and mission skills won't be worth it till this gets fixed or i know what to do to resolve it.

Since the whole splitting of the Steem chain, the whole ecosystem has been buggy for me. I suppose that is to be expected with witnesses dropping out.
