yes, i start building then i make caretaker for help my commander, but my caretaker focus my nuke for build it, i see the nanoparticle goes on my building but when i select my caretaker i see +0.3 metal and not -10,
then i make a second caretaker who dont work too, just my com work properly for build this nuke,
then i morph my com for a better speed building, and then my commander dont work anymore,
nothing cant finish my building
sorry for my bad english
