I have my four flood lights set up in xLights as a single strand, so I can run effects between them. I'm trying to set up some Valentine's day effects, but I can't get them right. When I use "Butterfly" (which is the effect I really like), the first two floodlights stay the same color and do not change. I remember running into this problem for my Christmas display too. How would I get the effect to work on all four floods?
