incubator as fix

Closes #2461 (closed)

We don't have activeSlave set here at all unless we are using it in husk, but if we are husky we aren't going there through AS dump.

Also, may as well return to incubator instead of main. In fact, if we return to incubator instead of main, I don't need to set up an equivalent to bulkSlave, we can pretty much just leave it as is. Players can keep clicking the link in incubator for each slave until they run out of ready ones, or they can turn on bulk dismiss, which is basically how it should work anyway.
