I finally got to LtC last night, since I am part Ferengi I had over 600k energy credits, bought ships from each class and was ready to stack them full of rare technology. I finish my escort, go to do my cruiser and it wont let me install a Mark IV Plasma Torpedo Launcher aft, even though I have one fore. Then i bought a 40k ec Mark IV Ambiplasma thing and it wont let me install that anywhere, despite the fact i have an identical one on my escort. Hopefully when i get home and log on it will cooperate. If i'm doing something wrong PLEASE tell me.
