I have been running into this annoying 'Floating Point' after creating a starting ship.
I get through the startup screen just fine, my mesh shows up okay. But after it gets finished generating the maps it gags on the ship at 98%, flips to the Game Start screen, then drops to desktop with a floating point error.
I have adjusted the XFile for the ship mesh (using notepad, it seems to be working), made the component map, and put it into playerstartships... I'm not doing something correctly.
On the installed components I cut/pasted the loadout from the basic human destroyer... do I need to make a completely new starting loadout from scratch? I get the feeling that's where the problem is coming from... ??
<edit>
Now it's progressed onto a game access violation error once I put the ship in the purchase que.
