I've added more than 9 weapons/items to a kit, and now I get random CTD?
There is no known fix.
I'm seeing black flickering on the textures of weapons/buildings/etc! 
This is called the "Z-fighting bug" and there is currently no known 100% fix. Best current remedy is "You could try "renderer.tweakNearPlane1p 0.1" and "renderer.tweakFarPlane1p 5" just add these to the Init.con of the mod. The default values are "renderer.tweakNearPlane1p 0.04" and "renderer.tweakFarPlane1p 15". Higher values for the near plane will allow better Z buffer precision (-> less Z-fighting) but too high will cause near culling and for the far plane lower values are better but too low will cause far culling."
