I recently installed SRTS and noticed the research node for the Orassan Quick Response Shuttle. When I researched it, I couldn't build it. It didn't show up anywhere in the building menu and it also would crash the "Try Place Near Thing" command and would just pop up with an error. I took a look at the error code and took a look at the mod files in the Orassan mod and SRTS to see what was different and I managed to get the Orassan Shuttle to work. It looked like to me that there was a chunk of code missing and chunk that didn't need to be there. So I snipped, copy and pasted, and it works! No more error reports. Could build it just fine and it works perfectly.
