This isn't really a bug. But an inconsistency on the MO website. There are a number of mistakes of the Allied Tech Tree and the Soviet Tech Tree sections:
The Allied Tech Tree points that the Strategy Center is unlocked from the Tech Center, while the Allied Structures section and the mod itself clearly shows the Strategy Center is unlocked by building the Airforce Command HQ. Also the Tech Tree section indicates that the Sonar Pulse ability is unlocked from only building the Tech Center; while in-game, a Naval Shipyard is also required.
The Soviet Tech Tree also shows that the EMP Mines and the Instant Shelter ability is made available from the Radar Tower. While the mod itself has the EMP Mines and Instant Shelter unlocked by building the Soviet Lab.
I also suggest removing Strategy Centers as faction-exclusive structures from the Allied Information section. Even though it gives different support powers for each faction, the essential building is the same and it's only stacking up useless cameos this way.
I also have this question that was bothering me for a while. If you have a Tech Ore Refinery and you lost your own Refinery, would that mean you won't be able to build Miners? Even though it seems silly to do so, it should be worked around to avoid that issue from anyone that might encounter it in the future, just in case.
