Are you sure there is gold in the second solution? Did you test with stannous chloride? iron gives a nice yellow color as well.
If all fails, you can cement any values on copper in your solution. Collect the powder, re-dissolve and drop again. As described in the section 'Dealing With Waste"
boiling off HCL? why? I believe you need a little HCL in solution to make the SBM work, but that will be confirmed or debunked really fast here
How did yo make the second batch? the same way as the first one? it could help explain what happened.
