[developers] (poosible) bug report: LKB doesn't generate on a different index

Dear Stephan,

You are right. I didn't pay attention to the issue that numbers must be 
unique across variable types, so my program only calculated "locally" 
unique numbers. And you just saved my day. I had quite some generation 
failure due to this "global" uniqueness, which buzzed me for quite a 
while. Thanks a lot!

With kind regards,

Xuchen Yao
