Hi guys, This is my first post and I have read the rules and I do apologise if I missed something important. 1) I am still on the 0.90 version, some of my mods are not yet compatible with the latest version of KSP, should I update regardless? 2) I do think some mods may be outdated, I will post versions to clarify. Now the issue: I have been building ships in the SPH, sometimes I would launch and I would be in the middle of the planet Kerbin. When I return to the SPH my ship is missing parts. Sometimes I wouldn't be able to select and move parts and the part toolbar on the left would be greyed out. I've tried a new install with all the mods added again and the same thing happened. Maybe it's the version of 0.90 I got from a link? (I updated only to realise some mods were not supported yet in 1.0.2.)
