I've been trying to make a new ship design that would be identical to colonizer but with a buff,  most of the stuff I copied from the colonizer and changed a name but I can't get it to show up in the ship designs and the game crashes with "Could not find ship design for Colonziers" and "Ship design definition could not be found in database" when I try to use it as a part of the starting fleet.
Only thing I could find and didn't define was stuff from the marketplace as there is no way it could get on it.

(The mod changes colonization modules and replaces the colonizer speed buff with a debuff and the starting colonizer to a different design so the buff remains)
