It looks like a vicious circle. The author of the mode has it compatible with the REP package, but with an older version, however, I haven't noticed a single problem yet, you have it compatible with the REP package. I tried to write a mod to the author, but I don't give much of a chance. Too bad. With both modes, the Cessna would look great.
