Ok, and let's add cl_qmap_count() check there.

Do you mean to resend NodeInfo request to the original location?
Assuming so, I guess it should be instead of second heavy sweep, and
it is a good idea. The only small downside of this I can see is potential
timeouts (and discovery slowdown). But anyway it is much better then
fatal error. Thanks!
