I got it to work but it only works once
I can switch to the second commandset and back again (i.e "Swtich To Set 2", "Switch To Set 1").
But then it doesn't let me. It says the upgrade has already been purchased... So It's greyed out... Thus it stops working
I also tried the "Conflicts With"... as soon as I started to build, It crashes.
The Production Update doesn't do nothing for this either...
Oh. Did I mention? I applied it to a building.... Maybe I should've started with that? Does it make a difference?
