From the Eggonicer's readme:
The Grendel & Ettin handling is disabled by default when DS Eggonicer is injected when playing an UNDOCKED world! :-(
This stops the Eggonicer from crashing when the AUTO EGG function is switched on for Grendel & Ettins, when there is no genetic information for these.
But if your world is UNDOCKED and you HAVE Grendel or Ettin Genetic information - ie when you have C3 Installed but are playing an undocked world or have Grendel or Ettin genetic files from another source copied to the "C
..\Docking Station\Genetics" folder.
Then if you start the game with the UNDOCKED WORLD, inject DS Eggonicer and then press CTRL+SHFT+C to bring up the CAOS Command Line Editor.
Then Type the following in brackets exactly (case sensitive,leaving out the brackets)
to ENABLE Grendel Handling - [setv game "DS_Grendel_Genetic_Files" 1]
to ENABLE Ettin Handling - [setv game "DS_Ettin_Genetic_Files" 1]
Then press CTRL+SHFT+C to close CAOS Command Line Editor.
If all goes acording to plan, this will enable Grendel or Ettin handling. If not try again :-)
