• Failed reflection calls to incompatible or otherwise invalid mods are now handled, so they don't stop the game from loading.
• Custom suits now show the corresponding icon in all relevant screens.
• Added an additional useCustomThreshold field to ModuleOrbitalSurveyor. Setting it to true will allow the module to recalculate the minimum and maximum altitudes beyond the stock values.
• When multiple versions of the same assembly are present, KSP now makes sure only the most recent one is loaded.
