I feel like while removing nanoforges from planets more or less works out, i think it would be better if the synchotron cores stayed. It leads to planets with high command being incredibly ***, with massive fuel shortages (holy ***, sindria is not okay) - not to mention fuel prices being very high.
Sometimes, i stare at how many credits it takes to refuel, and i cry.
Shouldn't Sindra be one of the few planets that
does have a Synchotron Core, since lore wise their entire "thing" is fuel production?
Perhaps there should be a white list for a few things they're allowed to keep, such as a Synchotron Core for the Sindrian Diktat and and a Corrupted Nanoforge for the Hegemony (given that they're known for their fuel and the size of their military respectively).
In order to make those harder to steal... is it possible to arrange it so you
have to disable their space station before being able to take it? It is a major part of their infrastructure after all, kinda noticeable if you take it. Then have a large, dedicated, defence fleet attached to that station that can't be lured away.... and as a result the only way you're taking that item is through total war.
