I am also having this issue. Where can I upload my autosave?

No, I am playing on Gleba and have not gotten to biter eggs. They litterally spawn out of no where and spawn arround my biochambers.
They spaWn on my space platform. They spawn on Nauvis when I make a 720x480 world and kill every biter. They spawn randomly out of nowhere.

This is really a bug. I have seen them spawn on top of concreet. I litterally watched them spawn out of nowhere inside my base

I understand the new recipes and fully enjoy them. However some my old blueprints for play no longer work as the base recipes have been changed. Is it posible to enable an option not to modify the base recipes?
