I've got a weird problem with the thermal rockets - basically, the model looks like there's thrust coming out the side and bottom regardless of the state of the engine (even when off). The thermal rocket nozzle also seems to clip through the ground. It also doesn't show up in staging. On the ground, motor not turned on - https://www.dropbox.com/s/x17oqxa3684gp6a/Screen%20Shot%202013-10-26%20at%2011.21.17%20am.png Engine running in flight. - https://www.dropbox.com/s/hd980ooedrtal2d/Screen%20Shot%202013-10-26%20at%2011.21.36%20am.png Stock 0.22 with just this add-on.
