I have transferred the ownership of the token by paying BTS tokens. There is a new owner but this owner cannot issue tokens. Should I move the token to the old owner. I think the system has a bug, that should be addressed.

Only owner can issue.

I have created an asset named HEARTBIT under the bzzrx user,  and I have issued 770.000 tokens. I have transferred the ownership of the token to user tnsl-ky. Now when I try to issue new tokens, the operation hangs. I can still send existing tokens but I can't issue.
