I'm actually have the same problem as the guy who brought this up - I didn't notice it at first, but when I went to build something with the Catfish as cockpit I couldn't find any other parts to match it's shape. When I saw your post I decided I'd take a glance at the error log, and lo and behold I have error messages for the majority of LLL parts. Log error example [LOG 21:12:42.748] GameDatabase: Assets loaded in 28.343s [LOG 21:12:42.750] PartLoader: Compiling Part 'Parts/Aero/Intake/part/LLLIntake' [LOG 21:12:42.786] PartLoader: Compiling Part 'Parts/Aero/Intake/part/LLLIntakeSmall' [LOG 21:12:42.795] PartLoader: Compiling Part 'Parts/Command/LLL2x1ASAS/kethane/2x1KethaneConverter' [ERR 21:12:42.797] PartCompiler: Cannot clone model 'LLL/Parts/Command/LLL2x1ASAS/model' as model does not exist [ERR 21:12:42.798] PartCompiler: Model was not compiled correctly [ERR 21:12:42.799] PartCompiler: Cannot compile model [ERR 21:12:42.800] PartCompiler: Cannot compile part [LOG 21:12:42.801] PartLoader: Compiling Part 'Parts/Command/LLL2x1ASAS/part/2x1ASAS' [ERR 21:12:42.802] PartCompiler: Cannot clone model 'LLL/Parts/Command/LLL2x1ASAS/model' as model does not exist [ERR 21:12:42.803] PartCompiler: Model was not compiled correctly [ERR 21:12:42.803] PartCompiler: Cannot compile model [ERR 21:12:42.804] PartCompiler: Cannot compile part Full log is bigger than post character limit, but will post in two batches if it can be of assistance. This is using a brand new fresh unzipped copy of KSP, and a newly downloaded copy of LLL. Tried twice (redownloading).
