Mission 5 Blockade Runner

I've recently started playing I-war 2 and I am currently stuck at a dead end. When I start this mission everything comes in double. I get two waypoints for the freighter convoy. I get explained two times what the mission objective is etc. When I finally destroy the mines and Marauders waiting at the Toadskin L-point I have to defend 2 convoys which are later on attacked at the same time, but in a different place. Naturally one of those conoys gets blown to pieces. If anyone could help me with this problem, I'd be grateful.

Is your game patched to version 14.6?

No, I haven't patched it to version 14.6 yet. Should I?

Probably a good idea...
