EMP vs buildings needs more experiment.
I suspect it is due to EMP + low power making powered buildings permanently unusable (visually animating, but object logic never recovered from EMP). Could be common if EMP affects power plants and they are targeted too.
I believe any powered building can be affected - this means base defences, production structures and superweapons. Base defences will no longer have attack cursors. Radars no longer give radar, Chimera no longer give stealth, Iron Guards no longer guard, super weapons no longer countdown, and ConYards can be perma-disabled (maybe until you unpack, never tried if unpacking is possible)
Generally, the building is still under EMP effect. And no other way has been found to recover it.
By any chance, were you at low power at the time when the buildings were supposed to come back online? If so, try again, but with good power, and then with different ways of shutting down power (spy, destroy power plants, EMP power plants)
I did some research.
1. Foehn EMP effects can be generated by EMP missiles, Raccoons and deploying Ramwagons.
2. To 'hack' (disable permanently) a production structure, let the EMP effect on that structure wear off while the structure owner is low on power. A 'hacked' building can no longer be assigned ready points or set as primary. It seems that the power status is checked after production structures are unlocked, EMP missiles and Ramwagons are therefore able to perform this bug.
3. To 'reboot' (enable) a hacked structure, let the EMP effect on that structure wear off when the owner has sufficient power.
4. If all of your production structures of the same type (E.G. Barracks, War Factories, etc) have been hacked, the interface turns black and you can no longer build units. To solve this, reboot one of these buildings or construct a new one.
5. If at least one of these buildings are online, the interface is not locked and you may build all available units, regardless of the respective building is online or not. Example: you have a good Soviet War factory and a hacked Allied War Factory, you can build Robot Tanks.
Special cases:
Construction Yards: Immune to this bug.
Barracks: Strangely, Soviet and Allied barracks are immune, while the other two are susceptible to this bug.
Shipyards: Immune.
Stalin's fist: Immune.
Clone Vat: Susceptible, but duplicates will still be trained from a hacked Vat.
Superweapons: Countdowns are unaffected, but the image sometimes gets frozen. (For example, Nuke Silo's hatch remains opened even after launch.)
