The department heads of choice change to something random every now & then (mostly when switching from ground to space). The bug is in here since LOR release. Why its still in game? Its such an obvious bug; nearly everybody playing STO must have encountered it by now; even cryptic devs who, at least as it has been told several times, play STO too.
Same with the bridge stations for the BOFFS. Lots of stations filled with noname NPCs instead of the boffs.
Did somebody at cryptic tried to connect the department heads with the bridge stations (seriously: awesome if thats what you where aiming for ) but instead messed up both? (not so awesome )
I have this bug too and it's a real annoying one. I've got plenty of Bridge Officers, whom I set up specifically, yet the game is tossing in the same Andorian Science Officer and the same Vulcan Engineer at all the stations.
