"Tech set to unlock recipe 'initial-wood-mutation', which does not exist?!"
Appears to be an intentional error case, but prevents the game from loading. I strongly suspect a mod interaction issue but I am running enough mods that it is probably not worth investigating manually. I can work around it by swapping the error with a 'break', but I have no idea what side effects that could have.
If you want the full mod list anyway, or want me to run an alternate version with expanded logging then let me know.
