aliens on the black market can not be purchased, unless you unlock them in the laboratory
aliens on the black market can not be purchased, unless you unlock them in the laboratory ...
This is ridiculous! 
if I unlock the aliens in the laboratory, then I prefer buy them there.
what is the sense?
The black market has always been the place where you have the opportunity to purchase units (using diamonds) that you're not yet able to regularly produce in your base ... this is the essence of the black market !
so... what sense does it prevent players from buying aliens in the black market ... unless they do not have them already unlocked in the lab?
considering the discount of 50%, today I would have liked buy some "heavy aliens" on the black market ... but the game has prevented me from proceeding, saying that I would have to first unlock them in the lab. 
and then what about the "strategic aliens"?
why I can buy "strategic aliens" on the black marcket, but not the other aliens?
this thing was ill-conceived!
please remove this impediment of the black market, as soon as possible.
