Change type / Colour palette bug


I've encountered a bug on 4.0.0, still current on 4.0.1 (hog 4)

If changing fixture type from a compound fixture (unexploded), for example Robe Spiider m5, to a non-compound fixture (Mac Aura standard) most of my colour pallettes values are cleared

I can reproduce this consistently on my file, haven't tried with a clean file
