Not that I'm complaining, as I find the Spider Hive Leader to be highly irritating, but on Unfair mode, the extra Spider Leaders on island 4 do not spawn any eggs and just hop to a new tile on their turn. If this is intended, great, I don't particularly like managing spiderlings and eggs, but if this is not how it's supposed to work, than the enemy is just wasted space against the enemy count and generally ignorable. Any one else seen this?

Edit: Just in case anyone out there is interested, the early September Changelog indicates that:

"Spider Boss will no longer spawn outside of its mission (only works on its mission) "

so the issue above should no longer occur.
