Yes, I know many people are going to think, 'It's his first post, what does he know!', but I'll save you the trouble and tell you not much. I've got a quite extensive list of mods that were all working rather well but I've just started having a little trouble after adding Tweakscale. I added it with the Infernal Robotics update to .16 but I've removed both and went back to .15d on the Infernal Robotics. Mod list: Active Texture Management, B9, Quantum Struts Continued, EVE, Better Atmospheres, Deadly Reentry, Dmagic Orbital Science, Editor Extensions, Fusebox, Fustek Station Parts, Improved Chase Camera, KAS, Kethane, KW Rocketry, Infernal Robotics .15d, Mechjeb 2.2.1.257, Modular Fuel Tanks, Docking Port Alignment, 6s Tubes, PandaJagerLaboratories, Part Catalog, Probitronics, Realchute, SCANSAT, Science Alert, SDHI Service Module, Ship Manifest, Texture Replacer, TAC LS and Fuel Balancer, Kerbal Alarm Clock, Universal Storage, Toolbar and Module Manager 2.1.5 Not in the list are all the little dependencies. Ones that I've had crashing with, either solo or not playing well with others: NovaPunch 2 (Not sure why... My computer just doesn't like it in 64-bit taking over 20 minutes to load it or crashing in the loading screen and no I don't have any logs that show anything that could help you figure it out. No, it isn't memory.) Tweakscale (I could possibly get a log for this one...) Infernal Robotics .16 (Tweakscale dependency) Interstellar (I think this is an OpenResource, Kethane, and SCANsat conflict of some kind. Best guess, since I only have problems with all three when they are all on at the same time) MKS (This could be a SCANsat conflict, but it seems to be more of a Kethane conflict. It won't always map out resources, even when I used the Kethane Debug menu.) Anyways, everything is the latest version unless otherwise noted. I run a Windows 8.1 64-bit pro (I know I'm so terrible!) and my computer's insides are truly irrelevant. While the internals are trivial, I think it does matter it you are running Win 7, 8, 8.1, or other 64-bit OS. Please post what your OS
