Got 2 named "Ultimate diabolical research" technologies (in german).
The first is in the tech-tier for the labs the other is a required tech for planetary invasion and is very expensive (something really messed up)..
Both techs says they are unlocking the Ultimate diabolical lab but only the one in the tech-tier unlocks it,but it does not unlock the ultimate...lab the lab disappears from the buildlist and you must use the Old tab to get labs...
