space shuttle system parts/part don't load

[Cracky2479]

I have all the dependencies of space shuttle system, though some parts seem to not appear in the sandbox. I for example don't have the engine mount in the inventory. Any similar issues or maybe even fixes?

Typically, you're most likely to get good info posting in the specific mod you're having a problem with.  Also, people are going to ask for a log file (see link below for how to find it).    I stumbled on this topic looking for a problem of my own but I don't know if our issues are related - moving from 1.8.1 to 1.9.1, I have at least 2 parts from 2 different mods not showing up in the VAB despite loading into the game (existing craft load fine, & I can load craft in the VAB but can't launch due to parts being unavailable).
