Thirdly we found a bug in the original mapping codes that added a miniaturised level 5 starbase under each planet, and removed it. This greatly increased lag when left in play. - That was a long time ago, and I can't remember if we cut the offending item before or after V1.1 was released.
Wait, how exactly did you remove the starbase under the planet? Can I do this in the 1.1 installation?
I don't think it was particularly easy fix.... mapping codes are a bit tougher than standard XML's. And the mod has a LOT of planets.
PR can you remember this one?
