Kerbal Space Program

If a craft is installed that requires parts that are not installed this makes the new space centre launch dialog not work at all, regardless of which craft you are trying to launch - stock, your own design or one of the mod's crafts. The launch button just closes the launch dialog, without going to the launch pad. The following exceptions show up in the log:

I know that this problem is not something that would be high on any priority list, since it is a result of incorrect user configuration, but this problem could be confusing for any user that has uninstalled a mod but forgotten to uninstall the example crafts for it. Please degrade the priority level if "Normal" is deemed too high.

1. Add a craft file that requires a part that is not installed to a directory that will make it show up in the launch dialog list (e.g. SPH or VAB in the stock Ships directory). For a good example pick a craft file from the NovaPunch mod.
2. Load an appropriate save (any save if the craft is installed in the stock directory).
3. Try to launch any craft that is in the same category as the installed incompatible craft (i.e. SPH or VAB) via the space centre launch dialog.
4. The window will close without launching the craft or loading the launchpad/runway scene.

• This problem does not occur if launching directly from the VAB/SPH.
• This will only affect space centre dialogs which show the unsupported craft(s) in them.

New as of KSP 0.21, due to the new launch dialogs.
