We are sorry to announce that we removed HEMAN wallet cause of source issues, same as we experiencing for BENJI.
We decided to remove HEMAN market before any order or deposit could be done so to avoid problems for users.
Best regards.
Do as you must, thankfully nobody sent any coins there yet since your announcement.
I can tell you right now there is nothing wrong with the source nor is it buggy just your implementation of things as YoBit have listed these types of wallets with random address length generation before multiple times with no problems whatsoever.
I suggest you work on your layout so you can list "all coins" since it was a very trivial problem that could of been rectified on your end.
Good Luck with your exchange.
