Did you know that Sectoids could revive your Mimic Beacon as a Psi-zombie? Crazy, right? This mod is basically just a fix for it. No more these insidious Sectoids will make your squad surprisingly face a complete clone of their still alive teammate for no logical reason! 

This is just a small fix, that marks Mimic Beacons as a non-reanimatable unit. It overrides the X2Effect_SpawnMimicBeacon file.
