It's sad to hear =(
Actually, this restriction makes this mod quite useless. It's a thing to play with, but not something that really makes practical sense.
Meaning, why I'll ever bother with revealing map over enemies nests (in any way), if I can just build artillery (with insane end-game range, especially) and forget about them forever?
Luckily, artillery does reveal map. But if I'm already shooting artillery, why do I need to shoot orbital cannon at the same spot?)
So, well... the coolest thing about this mod is voice lines. So enjoyable. But not a single practical reason to use it, unfortunately.
