Homeworld created in empty sector

[Makinus]

I'm doing some modding and, when i try to generete a map in my mod, it creates my homeworld in an empty sector, so, when i start the game it sais that i lost the game and the following turn will be my Last turn.... i looked everywhere and can't find the reason for this...

In my mod i basicly changed the planets/atmospheres created, where i changed the file secttypes.txt in the following manner:

All huge planets are Gas Giant/Hydrogen
Large Planets are Gas Giant/Hydrogen or Ice/None
Medium Planets are Ice/None/Oxygen or Rock/None/Methane/Oxygen/Carbon Dioxide
Small Planets are Ice/None/Oxygen or Rock/None/Methane/Oxygen/Carbon Dioxide
Tiny planets are Ice/None or Rock/None

I excluded some entries in secttype.txt of planets that the pictures don't matched with the new type/atmospheres and duplicated some entryes to assure a balanced generaion of planets for all possible type/atmospheres.

I also created a race that have a possible planet generated (Rock/Methane)...

Anyone have an idea what i'm doing wrong?

thanks
