This is in referance to the "White Wedding" mission of the Mirak Campaign addon for SFC2OP.
I've played through this mission several times, and every time it never completes. First I tried beaming the admiral directly aboard then heading to the planet, and beaming him down.. it worked, except suddenly it showed an admiral on the beam-in side of every ship. However, I did get the "beamed aboard" message. After that I tried capturing the ship, then transferring to it and making delivery personally. This worked, up to the point I tried to transport to the planet, at which point I had doubled admirals.. the beaming window showed an Admiral on both ship and planet but he was already beamed down. I didn't get any message saying he arrived on the planet, so I waited a couple mintues then reloaded and tried again. This time I tried to capture again, but the allied fleet captured first, at which point he beamed from the lyran ship to my ship... but because I hadn't captured I couldn't take him on the DN. I proceeded to the planet to beam him down and had the exact same problem. Not only that, but when I hailed the captured Lyran DN it responded the same way it had before it was captured.
Am I doing something wrong? Is there a bug in my copy of the scenario keeping me from finishing it? It looks like it's the last mission and I wanna finish it. I'm running a fully-updated copy of SFC2OP with the full 1.04 Enhancement pack(including models) installed. What do I need to do?
