Not a bug per se, but an oddity nonetheless:
I am playing as the Terran Alliance, struggling for control of Kwilas I - a nice planet currently under Altarian control. I am going for the influence route, and my strategy final comes to fruition when the Altarians join the Torians for a campaign against the Drengin.
The colony is mine - and my corporate trading partners are sad to inform me that "due to military tension", trade with the planet could not continue.
Maybe the game could check for the reason for trade-route cancellation and select a message accordingly?
