Hi firstly let me just say this is a great pack loving working through the 60's space program. I have found a small bug in the later Gemini missions though. In the Gemini-VIII mission the target vessel loaded OK but it didnt show for Gemini-IX. A quick bit of investigating showed that all the later mission Gemini-IX through Gemini-XI had an extra set of brackets in the ORBIT section of the config: ORBIT { { SMA = 705197.178599656 ECC = 6.00734955401844729 INC = 1.00172901748170448 LPE = 178.344718230958 LAN = 326.686242498989 MNA = 5.0835400450637 EPH = UniversalTime() REF = 1 } } Removing the duplicate set and reloading solved this for me. The pack was downloaded via CKAN and is version 1.5.0. Hope that helps
