I have a very similar problem. But I have a different system: Linux x64. After around 20 attempts to land precisely in target zone, I give up. Looks like this is a game logic problem. Here is all related info, including all my save games and some screenshots, in 7z archive (4.5 MB): https://drive.google.com/file/d/0Byka-cbwONilLU9vS1VWdkR4ZEU/view?usp=sharing Actually, after some entering and exiting ship, game crashed, but it is first time game crashed for me. So don't be surprised of logs ending. If you require more debug information, I can provide it. My hypothesis is that game don't believe object is actually in target zone, because of high altitude there (highlands >1000 meters). === Game info: === build id = 00705 2014-12-15_13-42-15 Branch: master Kerbal Space Program - 0.90.0.0 (LinuxPlayer) Steam BETA I don't use any mods. === System info: === OS: Linux 3.16 Gentoo n/a 64bit CPU: AMD Phenom 9950 Quad-Core Processor (4) RAM: 7860 GPU: GeForce GTX 760/PCIe/SSE2 (2048MB) SM: 30 (OpenGL 4.4 [4.4.0 NVIDIA 343.36]) RT Formats: ARGB32, Depth, ARGBHalf, RGB565, ARGB4444, ARGB1555, Default, DefaultHDR, ARGBFloat, RGFloat, RGHalf, RFloat, RHalf, R8
