So, I started a new game, on a really nice looking planet (blue grass, green water) and was excited. However, after completing cell stage, in under 8 minutes may I add, I did all the growing a brain thing etc. But when it goes into the history view, and you press the history button, it will play the cinematic of the cell swimming off the screen, and then during the fade out, the game crashes.
I've revised my mod list, and I don't see anything that would alter the early creature editor. That being said, the early creature editor selected from the menu seems to work fine.
Below is a the list of mods I have.
