Just throwing this out there, there's a few problems with this Plugin when running it under Linux. my KSP.log file can be found here: http://pastebin.com/mBG68UUv In the meantime, I was able to fix it under Linux by Symlinking the GameData directory to gamedata by navigating to the KSP directory and running $ ln -s GameData gamedata as well as renaming the 'WarpPlugin' folder to 'warpplugin' A note to the dev: The problem was caused due to the Plugin looking for a file that apparently didn't exist (see: KSP.log line #3191), but the file was there, the plugin was just looking in the WRONG directory (in this case, 'gamedata/warpplugin' instead of 'GameData/WarpPlugin'), this does not matter for windows, but in Linux and MacOS it matters a lot, because Linux/MacOS requires Precice filenames.
