Special Purpose Fighter "Bastard" cannot dock to "Silver Arrow" mothership. It just goes around to the tail and then stalls there. It doesn't bump or get stuck or anything, it just sits there unmoving.

Edit: Dammit, so many ships can't. I better divide the lists.

These fighters can NOT dock to "Silver Arrow" mothership:
Bastard, Raven, Gunslinger T

These fighters can dock to "Silver Arrow" mothership:
Matarice, Skolm
