Hi there, First of all I like to say thank you for producing such an amazing mod that I have now been using for 600+hours with no ploblems untill now, hence this post. I am hoping you can help me find the problem as I am dying to use the LEM and extra things you have added. I have downloaded and installed v3.86 (was using 3.74 before and all versions before that) but I have a few problems that I cannot seen to find what it is. With v3.86 installed I no longer get options to perform experiments using right click. I cannot do pod crew reports, eva or even surface samples. All the other experiments no longer have the right click options, the only experiment that works is the geiger counter. I have tested it on all the pods with the same results. I have removed v3.86 and installed 3.74 and all is fine again but I am lost as to what the problem is. I run about 60 mods in career mode and my system is stable as I leave it on all weekend for 24hours (dam kethane scans). I have reduced the mod count to remove the memory load but same result what ever I do. Current files loaded are 2.54 gigs and memory load at 27% utilized. Any clues?? thanks Hells PS keep up the good work, the best modeling I seen
