Hey csebal, I've used your mod in my mod:

thank you for your hard work with this
One small improvement I've made that I thought you could use:
On line 354 of csbmod_extplotinfo_Common.lua:
can be replaced with:
This makes it always show the amount of strategic resources, even if they have only 1, as might be the case when using the half strategic resources mod 
Also, on line 259 there's a small typo: ImprovemenType should be ImprovementType. Don't know what this causes but it kept showing up in the firetuner.

On line 354 of csbmod_extplotinfo_Common.lua:
Code:
if (pPlot:GetNumResource() > 1) then
strResult = strResult .. pPlot:GetNumResource() .. " ";
end
Code:
if (resourceType > -1 and resourceType < 6) then
strResult = strResult .. pPlot:GetNumResource() .. " ";
end

Also, on line 259 there's a small typo: ImprovemenType should be ImprovementType. Don't know what this causes but it kept showing up in the firetuner.
