I was having a little playaround in FRED with the Solaris and some wings, and noticed a few little bugs i thought i'd flag up. They're not very important but i thought as you were planning to re-optimise the ships you might get the chance to look into them while you were tweaking it;
A) When ships launch from the large middle fighterbay area, they have a tendency at the end of their exit to dive down and crash into the structure at the end of the lower prong.
B) For some wierd reason, if i tried to fly into the small yellowy-brown passages on the sides (the one's fighters fly out of sometimes) the game immediately CTDd. No idea why.
Neither is very important as the Toutatis didn't launch any wings when it appeared in game, but thought i'd mention them in case you wanted a Solaris launching fighters or recieving the player in any future chapters.
Thanks
