Is it true that landfilling swamps prevents expansion onto those tiles in Gleba?
Was told this and referred to FFF #424 when I asked how to deal with expanding parties on Gleba early in a run before artillery.
It specifically says this about Egg rafts:
"Egg rafts are the pentapod equivalent of spawners. They only appear in shallow waters of the various Gleba marshlands, which both you and your enemies can wade through. This keeps them away from the drier highland areas which are easy to build in, but puts them close to the areas where you want to harvest your agricultural products. "
Doesn't really say anything about expansion though.
I rushed to Gleba to get myself the biolab as I feel it is the most valuable building in the game early. Double your science output for free, and then some more because of more module slots for more productivity bonus.
