I just had a weird games with Even Weirder Worlds 0.90. I was playing a medium length game with the frigate and the Klakar ship didn't appear. I did find the Klakar homeworld early in the game.
I went through all the solar systems three times to be sure (and was several years overdue).
I had a really funny thing happen with this mod yesterday. I hired the Bloodfang, and every time I went into combat the Bloodfang was pointed backwards and had to turn 180 degrees.
I don't know if this was something with the mod, but I never saw it playing without the mod.
Actually, there are times when I'd like to have ships pointing in different directions when entering combat. Especially when I'm going to fight the Urluquai.
I've been playing your mod solid for days and not found anything like that. I actually HOPE I find it like that, as it would be useful in fighting the Urluquai.
