I just gave this new build a try. I tried to load up ported single missions from the DoP campaign, but it CTDs as soon as the first loading bar is illuminated. Using the debug build loaded with no errors however, and worked fine until some Hercs jumped in, and Bob's Herc uses 5 LODS instead of 4, which the debugger complains about. I reverted to your 14th build and had no problems. I haven't tried this with WMC's new build yet.
Also, with the slowdowns, lockups, and crashes in FRED non-HTL that the hi-poly models create, I've been recently opting to use HTL mode, but it still has some bugs. 1st is the object render position bug which I've brought up before, but I've seen some other bugs. Firstly, when you select a ship, the model mesh doesn't get highlighted. Also, some models don't display dockpoints or paths... mostly GTA fighters. I've noticed this on the Ulysses, Herc1 and 2, Loki, all bombers (except Athena in the Port) and I think the Erinyes. I'm not sure what would account for this.
Later!
