-The portup and shipwrightup points are good points to make. We would do well to move them over too as you suggest. The huge costs make them pretty prohibitive for anyone to build, but it probably would be best to lock them out of those govts and cities too.

-The grain silos do give a -1 trade. It is intentional though.

-Great forums do give a stat increase, but not to all factions. I'm not sure why that is the case. This might be something the stat guys did a while back, but it looks like an error to me, as the curia is two points higher on trade. Good eye on that too, but it probably needs asking about for confirmation before I submit the change.

-The irrigation one is not an error from what I can tell, but all farm and growth levels have been and are still in the process of being reconfigured. It is only available in desert areas, which have very low farming levels, so it is a big increase for those places.

Thanks!
