New sub models

[Gigalocus]

Basically, i choose the Asiatic fleet in 1941, and beging working my way up, and while i was based at java, i returned, and got offered a new sub, so i decided to trade in my Tambor, for this Gato, but, for some reason, im now docked at pearl, and it considers that my home base. So i load a save, and decline the offer. I then check my sub, and its a Porpoise ... WTF i think to my self. but i still smile as im still at Java, 2 missions later and im operating out of Australia (fremantle) and its my second mission out of Aussie, and i return after sinking the Yamato and kongo , and im offerd a new sub, so again i decide to take it, but wham! straight back to pearl. I could operate out of pearl, but there was a reason i choose not to in the first place, its too far off, and when you do find something, the green line on your attack map disappers, so torp attacks are basically impossible ..... so again i load a save and decline, but im still in my Porpoise, which i dont want, i want my gato, but dont want to go to Pearl, why does it keep doing this? or is there a way i can get back my green line so i can attack?

Thanks in advance ~ Gigalocus
