@astog.. been thinking about some of your "LOC_?_?_" strings and how the SQL datafeed seems to refuse their persistent activities -- and it all reminded me of another (Civ5) mod that offered us a custom options screen & which had the very same problems until they found a quick solution to define these special text fields within a different code context.
I can't recall the exact trick.. but it sure worked back then.
One thing is certain though -- this is the sort of design step that should be taken within a solid SDK and compiled with specific resources. Soooo - patience might be the only way for now.
